I prided myself on being self taught but once I went to a bootcamp and learned RoR in just 3 months from zero to working products.. it blew my mind how much having a good teacher around for 5 hours or so can do for you. Previously I taught myself js and it took 3 years to become decent at it. Teacher was able fill in the holes, give watch out tips, inform about parts to skip for now, show the big picture and keep momentum going.
