"Fear is the mind-killer. Fear is the little-death that brings total obliteration...."

"Do, or do not. There is no 'try.'"

Sorry for the trite quotes, but there is truth here. Are pursuing this project because it's worth doing or because you hope to get paid? First to market doesn't assure success. If it's worth building, build it. The worst you can do is learn something new. Your time is never "wasted" if you are having fun, learning, and developing your chops.
