I do what I love to do at the moment. If I wake up tomorrow and decide I want to dance that's what I'd do. Or design clothes. I think I'd throw myself into whatever I'm doing now. It's not about abandoning what I was doing before or giving up. It's about knowing that if I die tomorrow I lived the way I wanted to.
The ultimate end of human acts is eudaimonia happiness in the sense of living well which all men desire all acts are but different means chosen to arrive at it.
