Never open a single tutorial. You have to learn java first before starting watching tutorials. The best way to become a really big modder: open every code file mcp gives you. Look at the code, change some stuff, try if it works, and open more files and make connections with other files, and when you think you understand the whole code, start typing it yourself (never copy paste, because then you won't learn how to build a code), make you own source files inspired by the code you saw when opening all files...
This is how I started.
