I'm ultimately interested in everything and anything, or at least most things.

That's awesome. Me too, I get really deep into things. Btw if you have trouble with some maths, Khan Academy has good resources.

I want to understand where they come from. I still can't help but think they might have a foundation of truth.

This is great! You sound like a budding philosopher! My personal motto is "everyone has something to teach you, even if it's just a scone recipe." Some of the best information or perspectives comes from the most unexpected sources. E.g. on coding, I feel like learning weaving has taught me more about computer coding than anything else (I could never get into coding either, it just seems so abstract, but in weaving the strings take binary position, up or down, and they're grouped in multiples of 4, 8, 16 or 32. changing the sequence changes the pattern that shows up, and you can control the strings with punch cards. Looms were the first computers).

My personal rule on rule-breaking (taught to me by my father) is that you can break any rule as long as you know for sure exactly why the rule is there.

I don't think you're as easily influenced as you think you are. You're adaptable, willing to learn, willing to listen, willing to experiment and try things. If anything that makes you resilient to influence. When you listen to all different opinions, it's going to be hard for anyone to force you or trick you into any particular one. For example, since you've been here no one will be able to convince you that "TERFs are evil and want trans people to die" whereas a lot of people your age wouldn't even come here, so they can be easily convinced of something that isn't true.

If I am wondering if I should report someone who mistreated me, I will need to vent and ask for advice, because I don't want to do the wrong thing and I need guidance and support and to know if I thought right.

this is totally normal. We often call our most trusted people in similar situations for guidance. I'm 31 and I ask my friends for guidance on situations all the time and they ask me. Because we can make mistakes and misinterpret things and it's good to get an outside perspective. It doesn't make you weak or easily influenced. Again, it makes you less likely to be influenced because if you're in doubt you'll check.

I am exactly the same with decisions. I put a lot of effort into checking things out, checking and weighing every options. On the one hand it means that i never regret my choices because i know for sure that they were the right ones, but it's also exhausting. I'm getting better at letting go of things that don't matter as much but it's ok for you to want to consider everything before choosing.

Honestly, at 31 I'm staring to wonder if I have some degree of Autism too. I vibe with pretty much everything you've said, and I've noticed a few other things that people now tell me aren't actually normal. But I don't think it matters. If I do have it I'm high-functioning enough that it's barely noticeable. It doesn't matter if you are autistic or not, you are in control of your mind and your thoughts.

You seem like a really cool person. Genuinely, I think I'd really like to hang out with you. I don't think you need to be afraid of yourself. Follow your mind and your heart and your courage wherever it leads you. You're going to do great things!
