I’m with Brad….and to take it a bit further….
Happiness occurs as a by-product of working towards a goal, either your own or someone else’s.
Happiness doesn’t necessarily come from achieving that goal…but from working towards it. The events that happen on the way can provide all sorts of new directions and opportunities…but the trick is to start moving towards a goal…and see what happens.
From what you’ve said, you appear to be doing that. Enjoy the ride and don’t be afraid of detours!
