Please please study the tools and the principles you use. No schooling will offer these things you learn then through experience. If on your own then that takes a long time. To expedite find rules like Sandi Metz's rules and S.O.L.I.D. principles, Learn OOP patterns and code smells. Don't worry if you don't understand why these rules and principles are in place just follow them. You'll eventually get there and the code you produce will not cause catastrophes later on. But if anything this simple rule is the best: K.I.S.S. (Keep It Simple and Small) Make small things. If you ever find yourself saying "do this and then do that" your talking about two things and make them two things (separate functions/objects) and name them.
