I had it in my head (since I need my salary to pay my bills) that I would continue working full-time until either a) the business earned enough that I could quite or more likely b) we secured seed round financing so I could pay myself and my partner a livable wage.
I was at a networking event yesterday talking with another entrepreneur and he was certain that I had exactly 0 chance of securing any funding if I was only working on the business nights & weekends, that I needed to quit my job first before searching for funding. If I quit my job, I have about 3 - 6 months before I'm completely screwed and lose everything, and I'm on the cusp of starting a family with my wife, so I need to be a little more reasonable with this. It's not that I'm not dedicated (far from it) but I just can't afford basically to quit my job without supplanting at least a decent % of my income so I can make ends meet.
