“And that brings up an important point. If you start a business, there will be doubts. Lots and lots of doubts. There will be days when you’ll take $5 for the whole mess. There will be days you want to quit. These doubts, and these dark times, will be far larger than anything you can imagine if you’re working for someone else, even if the company is muttering about downsizing and layoffs. Because the whole mess is on you. There’s nobody else to fall back on. There’s nobody else to blame.”
