Welcome to the Forums! Glad to have you aboard!
You've come to the right place to learn what you need to build models. The members here are very knowledgeable and are always ready to help out with any questions/problems that you may have.
I've been building for 70 of my 76 years and build whatever strikes my fancy at the time. My advice to you is to start off with something simple like a 1/72 plane from a manufacturer that has "snap fit" kits. They are easy to build and most of them do not have as many problems as the newer many, many, many part kits. They will let you improve your talents as you get a few under your belt. They will let you improve your basic skills. Then as you get better with them, you can step up to the larger, more complex kits. Then, as you move to these kits, you can try out the weathering, scratchbuilding and other skills. I'm still learning new skills with almost every new kit that I build.
Hope that these tips help you. Don't be afraid t ask for help. That's what we're here for.
Good luck. Don't forget to post pics of your builds.
