I understand that one-half of United States businesses fail within the first five years. I expect far more than that fail, if they are high-tech startups. Consider that I read just a few days ago, that - overall - venture capital earns 5% less than the S&P 500. However, some VCs make out like bandits, it's just that there are lots of clueless VCs. So if you start any kind of business, you really don't want to quit your day job, until that business is profitable, or if you do quit your day job, you want to have lots of cash in the bank.
