I too am along in years. In my younger years I had the good fortune (misfortune?) of being brainwashed about the sanctity of art. I sowed my wild oats wildly right after architecture school (4 years backpacking in Europe, art school and 10 years doing photography, into guitar playing for a long time (12 Strats) getting my first archtecture related job when I was in my early 30s. So basically I took care of my bucket list in the beginning instead of at the end.
The point being, in my case, that you focus on what's in front of you and just keep growing. So I will just keep doing this (could be anything - I like image making) as long as I can. It might be harder to do if your significant other is more traditional but luckily my wife is a painter so we're on the same wave length.
