Entrepreneur, Feel the Burn

Feel the Burn, originally uploaded by davidjwbailey.

Chillis are uncomfortable at first, but cause no real damage to human tissue in normal doses. After a few minutes they act to reduce pain as the body release massive doses of endorphins and anandamides in response to them. A few minutes later a massive feeling of relief and content usually follows. While not addictive, many people find this a pleasant habit and regularly take large doses. Why does this remind me of running start-up companies?
