When you were learning to drive, did your dad ever tell you to "brake early" or "shorten your sails before you dock?" Man, I just wanted the GO pedal and loud rock. I think your first startup is like that as well. Quit your job, hock your house, cancel your healthcare, work 1000 hours a week, and spend your money before your IPO. Then you run out of money, layoff everyone, and go back to work at your old job, slightly embarrassed at what a yerk you must look. But, oh, my, a little pause at critical points can really avoid a lot of that.
