Just do whatever makes you happy. A job that you love is worth it's weight in gold. You've only one life, so go for your dreams. I went to Uni at 33 because it was a life-long ambition, and now I work for myself as a traditional decorator. I don't earn a fortune, but I enjoy my work, and apart from sleeping work is the biggest time swallower of all, so make sure you're doing something you enjoy or you won't be truly happy.
Only you can decide what that will be, but don't get to 60 and think 'what if, or if only I'd.......'
