You should do some data analysis on where you are spending most of your time when building software and see if there is a way to do it faster. You can read books and follow someone's advice but nothing can be more useful to yourself than trying to navigate your own mind space in search of answers that you are looking for. If you figure out that you are spending most of your time deliberating how to name variables, you should spend time reading about programming styles. If you spend time debugging, identify what sort of bugs you are creating and try to go over books that cover most common programming bugs and try to incorporate them during programming time itself.
