How do you get money for your living while you are starting a business?

Well, I am considering to drop off the job I had now..
I thought I need to focus on my IM as it is starting to grow up.. Though, the profit is still only $10 every month. (not enough for living)

The problem is that my job limits my business to grow more. Due to my job's location, I lose a few potential customers.

But if I lose my job, I will lose the income that support my daily living.

Have you ever in the same position? How do you overcome this?

Need a lot of inspirations from you…
