How quitting my corporate job for my startup dream f*cked my life up

Most of the comments here are pretty harsh, but I think the author has some really good points. Maybe not everyone is impressed by his former management consulting job, but even if you aren't, quitting your job (or forgoing a regular salary) to do a startup is probably not going to be supported in everyone in your life. My personal experience has been that most people have been supportive, but I live in the Bay area. My parents try to be supportive, but I think they think I'm crazy/foolish and keep it to themselves. Social pressures can be a big hardship, having support from friends and family can make things a lot easier.
As far as money goes, he is totally right. Having savings to live off of for a year+ is a wise plan. (But so is living frugally from the first day you quit your job, and perhaps bringing a refillable water bottle).
If you don't have a plan, money can quickly evaporate. Very quickly.
