The most successful inventors I know are passionate about their ideas. Makes sense, doesn’t it? Becoming an entrepreneur isn’t for the faint of heart. I can tell you this: Everyone who makes it experienced rejection countless times before. It’s inevitable. To play this game, you have to be willing to keep at it.

You have to let rejection roll off your shoulders. You can’t lose sight of what’s at stake. Being personally invested can really help. Because when the going gets tough, what’s going to propel you not to give up? Purpose. When you’re passionate about your mission, nothing can stop you.
