Failures are great. You learn the most from them. You learn way more from failures than you do from success (At least that's been my experience). Most of my business ideas have failed. But the few that have succeeded have made it all worth it. So keep pushing. My advice would be to start with WHO you want to serve and what problems you want to solve for those people. It makes it a million times easier to succeed with your business when you start it that way.
