Most business attempts result in failures. For most if us, life itself is a row of failures, punctuated by brief successes. And those successes will be shared in the media. So you mostly read success stories (who is interested in failure, anyway?).
You as an entrepreneur can learn three things from failure:
1. You learn to overcome failure.
2. You learn how to deal with (the psychology) of failure.
3. You learn that failure is a necessary hurdle on your way to success.
If you fail often you will succeed often. If you fail fast you will succeed fast. Keep failing until you accidentialy no longer fail! We call that persistence.
