What in the world is a person to do with 
THIS?  Too much of it is all too true. I have dabbled in ten or eleven of those favored careers; not as careers but as activities at one time or another.  I did work as a librarian, television production teacher and have done a fair amount of video editing.  And put together a couple of books and wrote a few poems, taken a few photographs.  
I concentrate on those things that make me happy because the other side of the coin is painful and there isn't much to be very optimistic about.  Daydreaming is just a bad habit. Wounded at the core is close to home. A hermit. 
Poor, pitiful INFPs.  Some person from Finland googled my subject and sent me off into this.  I am going to go bake a cake, not on impulse, but it is a plan and if I preheat the oven I will have to follow through.
