I started extract brewing in March of 2012. After about 7 or 8 batches, I switched to all grain in June of 2012. The first two all grain batches I brewed, I made from scratch. Then second of which was a cherry stout, and to my surprise, it took first place in the region of the NHC this year. I ordered a handful of all grain kits after that, but I do all my own at this point. I got my membership for the AHA for Christmas and have learned so much since then. You are at the benefit of having infinite brewing education at your finger tips. If you're asking this question, you must think you are or close to being ready for the transition. So I say go for it! I feel that brewing a beer from scratch is much more rewarding than using extracts and kits. Good luck!
