the art of what is next...

So...

If my carpentry career is winding down, what is next?

Was just talking with a buddy the other day and he posed the question: 'Do you ever have those days where you feel like you are just okay at everything: an okay carpenter, an okay guitarist, an okay surfer... but not truly great at any one thing?'

Well... I want to be done with those days. Been having far too many of them. Any suggestions what to dive into? Something that won't be another three years and done?
