The thing is, building a billion dollar business doesn&#x27;t require 1000x the work or entail 1000x the stress of building a million dollar one...even if it is more than 1000x less likely. It&#x27;s also the case that only getting 5% of the way to a billion dollar business after six years is probably going to feel better than 20% of a million dollar business after two years...one comes with a reasonable paycheck, the other doesn&#x27;t. Finally, the investors in your million dollar idea aren&#x27;t going to be any less assholes, and probably moreso; your credit card and local bank are less ok with failure than angels and VC.<p>To put it another way, building a lifestyle business already requires a huge amount of luck and time on top of the hard work and stress. There are only so many trips to the plate and swinging for the fence may be the rationale option.
