I am betting a little more. I have a ambitious startup that has no middle term, is 0,00001% of chance to make me a multimillionaire or 99,99999% of no revenue at all. But in the meantime I am starting a less ambitious, more solid SaaS business, with more equal chances between small loss and decent profit. Ok, I had to quit my job because in top of that I had to learn to code. But my savings are in the most conservative investment (treasure bills). But my idea, if this small SaaS doesn't give me enough money until my reserves end, is to come back to a day job, while still pursuing the sustainable business trajectory that patio11 sugests. This is similar to Taleb investment strategy, simultaniously doing a highly agressive investment and a highly conservative one.
