It's the common creative's problem of: what you can imagine vs. what you can produce (aka "moving the goalposts"). When you first imagine a solution, of course it's great and inspiring and you want to dive in. But after time it becomes "work." Worse, your imagination can see more to add to the project - to make it even better! Meanwhile, the longer you work on one project your imagination starts to think up solutions to unrelated topics... and those are now better because they're fresh. The simplest cure - recognizing this is a natural paradox for the creative process. This will reduce the massive downer to comes from not chasing every dream and at the same time provide long lasting satisfaction through respecting the few you picked and stuck with.
