Drawing is a good pastime. I paint in intervals, last year I experimented a lot with watercolours, but at the moment I write exclusively. Your teen drawings reflect what you were interested in and it's nice to see kids just picking up pens and trying. It's true, your wife is way ahead of you and a comparison is pointless. Everyone has their own talents. You certainly had potential and if you had encouraged it, you would now be many developmental stages further. Art is just as hard work as any other work in which you want to achieve something. So your interest in art has let you get to know your wife and you support the artist scene. That's very good, because that's what art needs: Interested parties.
