workaholic to paint my masterpiece

I have one last thing to change, I think, that is my mind.  I have come from years of being a workaholic.  I can't work anymore and now I don't know what to do most of the time.  I must convince myself that I have the time now to "paint my masterpiece", but it is not easy to do that.  It has just been 2.5 years, and I am young.
