I’m not sure why you’re getting downvotes exactly.
A basic tutorial on web development like Sleepless One suggested is definitely a good place to start, just to get a basic overview of what you’re getting into. I personally learn best by doing rather than by learning. What I mean by that is if I sit down to try to learn… say… the C programming language, I’m probably not going to learn much from it, let alone retain it. But if I decide I want to write a game in C and start writing the game even from what little I know about C, I’ll learn as I go. Not to say for me there’s no benefit in a “learn C” tutorial, but if you’re anything like me, I’d recommend switching to doing the specific website you have in mind as early as possible rather than trying to “learn web development” before switching to the project that is ultimately your end goal.
Beyond that, you’ll want to avoid falling into a trap of doing what feels to you like it’ll work rather than what’s “best practices” for “the industry.” So the other thing I think will benefit you searching-wise is to look for information about not just how to make it (technically) work but also how to do the thing you want to do “right.”
At least that’s my recommendation.
Beyond that, are there any existing websites that closely approximate what you have in mind for an end goal for your project? If so, could you share one? I think it might help us with more specific recommendations.
Definitely not too weird a question!
There are plenty of introverted Americans who hate how extraverted it is here. And the U.S. definitely isn’t “superior” to Germany in that way (or any other particular way.)
Also, there’s a difference between introversion, shyness, social anxiety, an avoidant and/or schizoid and/or schizotypal personality type, an avoidant attachment style, hikikomori/shutins, autism, and plenty of other sorts of socially-averse sorts of temperments. Some are “problems”, some aren’t. Given the way you’re talking about yourself, it sounds like what you’re experiencing is something you’d like to change about yourself. I do think it’s worth introspecting a bit (see what I did there?) and seeing to what extent your desire to change is internalized shame put on you by others and to what extent changing your presentation in the world would lead to a truer expression of your true self. But assuming the latter is the case…
Practice. Even if Germany is a pretty introverted place (and that’s valid – there are definitely differences regionally with regard to how introverted or extraverted the culture is) there are definitely places/events/gatherings/etc that are more expressions of extraversion than others. Immerse yourself in such events. Baby steps are fine. Start with contexts that are just a little bit more extraverted than you are if you like. And move on to more and more extraverted sorts of contexts. Also, I’d try to focus on events centered around things you hold a genuine interest in. (I, for instance, have enjoyed a lot of tabletop roleplaying games. That activity, even though it’s engaged in with others, feels much less overwhelming to me given that everyone’s focused on a common activity rather than just on “each other.”)
One more word about this. Try to avoid “masking.” That is, don’t invent a facade of extraversion to show people. It’s very cliche to say it, but: “be yourself.” I think probably ultimately if you end up “pretending to be extraverted” rather than engaging in socialization in a way you genuinely enjoy, it’s likely to do you more harm than good with regard to your goals.
Good luck!
