It took me a few years to get out of the "I can ferment that" phase, where I wanted to experiment with everything.
This is a great point actually. Something that really helped me along the way is I stopped trying to brew something new and different every time and really concentrated on nailing a few choice styles of beer. What it did is eventually (after a few tweaks) eliminated the recipe as a variable and allowed me to concentrate on the process. Repeatability being the goal, I really was able to perfect my brewing and now I can revisit recipe development with the knowledge that my process is (more or less) solidified.*
*I think brewing is a practice, much like medicine, and there are always new innovations, techniques and advice so you are never done learning.
