How much $ per day for you to turn pro?

I am curious to see what type of responses everyone gives here.

What amount of money would you need to average per day playing poker to quit your regular job and become an online poker pro.
By quitting your job you will be losing health benefits and the office enviornment where you have social interaction. At the same time you will no longer have deadlines or have to commute to work.

Is it $150 a day? $250 a day? $1K a day?
