Something will look great on paper but will never work out on action. Some accidents may reveal the best strategies/business ideas. So it is better to keep doing and trying new things and fail, you will find new gems.
Derek Sivers, founder of CDbaby said that "Quality comes from quantity and you have to keep trying but use different approaches, this is persistence."
Start doing and don't wait till you make it perfect, that way you won't be able to finish it. Perfect it over time.
Hope this helps someone, somewhere
