Excuse yourself by falling back on the theorem that failing is good,
and you will never have the determination to push through those moments where success seems impossible.
Forget this notion that failure is good. Only remember it after you have, in fact, failed. Not before.
There's a lot of things that have to line up to make a startup successful: vision, market, funding, and talent. Believe it or not, the market and the funding are likely to be more forgiving of previous failure than the talent.
I think far too much business and start-up advice is nothing more than anecdotes and personal experience, none of it backed by hard numbers. (Rework is no exception.) Are there any books out there where people did actual research to back up their advice?
I guess I make an assumption here that becoming a better person by developing credibility & confidence helps you as an entrepreneur. Would you agree this may be the case for some young entrepreneurs?
If you've got a 10% chance of making it each time, just keep trying 22 times and you'll success 90% of the time.
