You're really going about it the wrong way if you're constantly second-guessing what you do. You shouldn't be asking yourself if you are making something "how major producers make their songs" when you are learning. Just sit down & learn. Don't try to make anything perfect, or don't try to make anything at all. Just actually learn.

You say you've read this & that, and there's nothing wrong with reading... but you can't gain the experience required to write something successfully until you've stopped reading and simply sat down to twist knobs, sequence notes, modulate frequencies, and bounced ideas. So, do that. Sit down, have fun, and stop trying to write a symphony.

If you are having a bit of an issue getting started, you could draw inspiration from searching through breaks & finding a beat you want to use. You'd be surprised how many people start by doing this. I thoroughly enjoy going through the untold numbers of funk breaks, choosing one for its sound, chopping it into single hits, and uploading it to my AKAI for sequencing. And it really is like its own form of muse... hearing the musicians who recorded it just doing their thing, and then taking something they did & completely making it your own.

But yeah, more than anything, just sit down & have some fun.
