It's a wonderful idea! Every so often someone calls me with essentially the same concern, they really want to restart the guitar after a very long layoff. Most actually stick with it, at least caually, but some really take a shine the second time. There's nothing to loose and lots to gain in self-amusement/enjoyment/awareness/image and potentially a whole new or renewed social base.

Be encouraged. To paraphrse someone much more perceptive than me, "Everyone wants to be, but the real fun is in the becoming."

Peace, Mooh.
