I taught myself to play the guitar, and I have been playing for 30 plus years,  I also play with a couple local groups here.   I found that to teach yourself your must be very dedicated to  learning the proper way to play.      I spend 1 hour a day everyday with my music.  I will not settle for less, this is my time and my family respects this and leaves me alone.  I also taught myself to play keyboard, at which I am very good .    I would say whatever works for you then go for it, but really give yourself to it.
