Totally frustrating T_T

After 4 days *or more, I don't remember anymore*, I'm completely frustrated. Why?
I'll tell you why: web-designers and other people that develop software, advisers and sites never-ever agree on how, what, and where to do things.
I know that it's all about taste and how you deal with things, and there's not really an "absolute true answer" to how you can code Actionsript, but why the hell all them just don't make sense? I mean, I tried, tried, re-tried, changing everything, and when I say everything is ABSOLUTELY EVERYTHING. To the point that I re-started to make it from scratch, opening a new file.
Tried to follow book-guides, video-guides, forum-guides, blog-guides, and all kinds of guides I could find and NONE of them worked. ALL gave me warnings and incompatible lines that didn't let my buttons to work properly.

My Flash compiler will always return some kind of error, even when I just copy+paste a code that is at a digital book and try to run it. I tried to type it myself, watching videos and revising over and over again all the lines, and just didn't work.

OK, I'm a fail person, but really, trying so many times and never getting ONLY 2 BUTTONS to work properly is really, really, really frustrating.

I can make the button work and play what I want, then the second button does what it should do that is going back to the main screen, but after that ANYTHING works. It was supposed to go back to the first step of the process and allow to just click the first button again to make all the process like a loop, but just don't work.

Now I made a decision to just throw out all the things I collected trying to understand the f****** coding, and try to do it like I always do: by myself trying to figure out how the software works.

I should have learned over all my lifetime that no matter how good a book, class or teacher is, I'll always learn better trying it by myself. Yes, it takes a lot more time, but works better at the end.

Even taking a look here and there, and trying to follow some tutorials, my Photoshop skills were all conquered alone. And now, when I try to make something watching or reading a tutorial, usually I'll just think that there's a different *and sometimes easier* way to do some of the steps.

Actionscript is a completely different environment, and have a lot more hidden things to undercover, but now that I'm frustrated enough with everything I saw around, I'll just HAVE to learn it myself OR I'll never rest in peace if I die.

WHY?

Just because I KNOW I CAN DO IT. I only need to figure out how to find what I need inside the codes, and they are all there. I mean, it's not like something you need to search outside the software, like PS filters, brushes, fonts, whatever. All the codes to make things work are there, I just need to find them. And finding them means understand how the logic behind it works.

Oh, my, I know that I'm not the most logic-like person, and that probably I'll never have all the basic codes memorized, but learn how things works doesn't mean that I NEED to have all the codes inside my brain. And let's be real, why the hell I need to have them inside my brain when they are all at the software and all I need to do is navigate to the place they are stored, click it and it will just be placed at the screen?

Ah, I'm feeling better after putting all that rage out of me... LOL.

Talking seriously now: I don't figured out why people keep telling "memorize the codes", when no matter if it's just the most ridiculous thing, like making a button to be clicked and load the next frame, there will be tons and tons and tons of different ways to do it because each one has a different way of doing it and thinks that it's the better.

So, if all of them can have their own way of doing it and think it's the better way of doing, I can find my better way of doing it too... LOL. Maybe that's why there's so many ways of doing it?
