Here are my 2cents.
You need something to show you how to load film on the reel, what chemicals to use and in what order to use them and something to show you how the enlarger works. There are countless books to show you that.
With that information in hand, you then get as much film as your pockets will allow, and you go photograph.
You might try looking at photo books (monographs) to see what you respond to, and photographing those subject. Just experiment; it will keep it exciting, and it will keep it fun.
Good luck and have fun.
