For me, it's following through with what you say you're going to do. If you don't plan on doing it, don't bombast everyone with how amazing it's going to be and how awesome you are... just do it and the results will speak for themselves.

Also, the results are usually for me and my own sense of accomplishment, so why would I care about sharing them in the first place, really?

I'm pretty impermeable to other people's opinons, as a result... which I think blends introversion with alpha.

You sound like an INTJ, maybe besides the journaling... maybe an INTP. (these are myers-briggs types.) I've met several INTJs or INTPs I'd say are alpha males, for the most part. Both of those can learn skills if they care to, including leadership, entertaining, etc.

Don't confuse extroversion with Alpha.

Alpha is more of a philosophy of approach to life.
An alpha lives their life for themselves.
An alpha is just as happy alone as he is in a group. An alpha isn't the one grasping for attention. He is doing his thing, which gathers attention because it it interesting or useful or entertaining.
An alpha will treat everyone the same; his responses to people define his frame and every one outside it can evaporate.

You can be "alpha" by doing your thing, enjoying your thing and not letting trivial social constructs get in your way.

In terms of pickup or game an alpha is not the roided up jock that fucks all the sluts.
He selects from the pile the ones that have value beyond their genitals and makes it known that he has interest. Their is no pursuit, an alpha courts and seduces.
And the woman will want him because he has value beyond money or looks. Being good looking and rich helps though, but not in the long run. Your actions ultimately make you successful.

Don't let introversion define your game, make introversion an element of your method and integrate it into your game. Flip the picture and become more than merely an introvert.

You think the strong-silent archetype invented itself?

Are you an introvert or do you lack social skills? Perhaps it's both. It's tempting to judge your value on your good points and then rationalize away your weak points. I did this for a long time with my physical fitness before realizing that my attitude towards it was really a bunch of excuses. The same applies to my social ability.

Everything can be learned. Warren Buffet had a difficult time socially, but he overcame it with hard work (and the book How to Win Friends and Influence People). It was important to his plans, so he set out to improve it.

Most people have no fucking idea what an introvert is. Let me simplify it for you.

Your brain processes information differently than extroverts. That's it.

You can be outgoing. You can be social. You can be aggressive. You can be outspoken.

You just need to have moments of reflection and meditation to "recharge."

A real introvert should function pretty much the same as anybody else, they just go home a little earlier, or want to spend some time alone once and awhile. Don't use it as a crutch or excuse to shun social interaction, or for that matter taking what you want in life.

One important aspect of being Alpha is taking yourself out of your comfort zone, but how you handle your personal relationships should be no different. You should have a bit of a leg-up on extroverts as you won't want to talk about your feelings very often.

Never talk to women about your feelings. Haha.

Introvert here. The answer is yes.

I'm an introvert because I need alone time to recharge my batteries (solitary walks through the woods are great for this). However, I love being social with people. I just have my own style of doing it. I don't speak much—I stay laid back and observe everything, and I'm constantly analyzing things and coming up with plans in case certain things happen. I'm an asset to the group because just having me around means you'll be safe in a crisis. I'm like James Bond or something.

People feel like they can relax around me and have a good time, because when the time calls for it and things get tough, I step up and take charge with a plan of action. And once in a while I throw out a witty one-liner to get people laughing.

So hell yes, you can be an alpha introvert.

Growing up I thought my uncle was as Alpha as fuck. Whenever we went to visit his family he'd always sit aloofly in the corner reading his paper ignoring us. I always felt the pressure to be social but he just seemed not to. I found out when I was older that he suffered from crippling social anxiety, which is why he exhibited most of your 11 bullets, yet he came across as the most alpha guy I'd ever come across.

The "Gary Cooper" strong silent type is a classic introvert alpha.

Some examples:

Rick Blaine (Humphrey Bogart) in Casablanca, or pretty much any Humphrey Bogart role.
The Driver (Ryan Gosling) in Drive
The protagonist in pretty much any film noir movie.

This is me. I'm an introvert. I've also learned to enjoy socializing more as I've gotten older. Learning pick-up helped tremendously. Also, having open relationships helps. The potential for sex is a huge motivator to get me out into social situations, so I tend to get very anti-social when I'm in monogamous relationships.

That being said, I'm very Alpha and I'm very good with women (post-pick-up / TRP). Introverts can be great "benevolent leaders".

OP, "alpha" is very contextual thing. Say, you are friend with not so hot girl and you act naturally, aloof, DGAF - she sees you as alpha that you are and is getting gina tingles when you're around. Then you meet really hot chick that you see as "out of your league" and suddenly you don't know what to say, act like a dork - she sees you as beta and you are. But you are still the same man.

Or, another common example, husband gets betaized and his wife is repulsed and not giving him sex anymore. Man gets fed up and gets into affair with a coworker who is enthralled in him and they have plenty of hot sex every chance they get. Is this man alpha or beta? He's both actually: beta to his wife and alpha to his lover. Same man!

Think about that for a moment cause then you'll realize how your question and line of thinking completely misses the mark. You are not introverted, you chose to act like that. Once you start thinking about how to change that behavior, then it's only matter of time when you'll start reaping rewards.

Or to answer the question directly:

Can an Introvert become truly Alpha?

Yes, people can change, happens every day. First you fake it, then it becomes a habit till you no longer have to remind yourself to watch the body language, pause for a moment to think of what's the proper response to that shit test ... it becomes second nature. You're no longer faking it. The hardest part is the initial fake phase - you start practicing new things that feel odd and unnatural, while still questioning yourself, thinking on quitting and searching interwebs for better and superior strategy. This is the part that you have to push through, there are no shortcuts, it's essentially a test of will (and faith). But then one day you start getting results, nothing stellar cause you're still making lots of mistakes, but it's finally something. At that point you no longer need "motivation" (seriously motivation is for losers - real winners draw their strength from discipline and habits), you have results, proof, from that point on you just keep walking the walk, there are no more doubts, this whole process becomes a workout routine. So, start thinking in terms of "what specifically I need to change", pick one thing and start practicing.

If you're good looking enough physically/have enough social proof/status, sure lol

These are all traits that make you small. An extra at best.

So is it possible to get away from these genetic traits introverts have and become the alpha?

What would you say? Can you overcome these traits? We can't tell you what you are able to do and whot not.

genetic traits

Are you serious? That's a shitty excuse for yourself.
