Music was your real passion this thing you held dear even above family. It was this relationship that never betrayed you. Once it became your job - this thing that was highly visible this thing that became about commerce - that's when you were holding onto music like it was a palm tree in a hurricane.
With engineering I view this year's failure as next year's opportunity to try it again. Failures are not something to be avoided. You want to have them happen as quickly as you can so you can make progress rapidly.
