Congrats,
and as I was told after graduating (many years ago): "Welcome to the Real World"!
My only advice is not to forget how fun it was when you didn't have the adult pressures of the world brearing down on your shoulders, because sometimes the simplest pleasures are the most fullfilling.
Since you fish, you already have a step up on all the rest.
(I have an older brother that had just gone through a nasty split with his ex, and now that he has taken up fishing (due to my influence), he knows one perfect way to relax when those pressures come bearing down on him.)
