When should I start freelancing?

As someone who has recently made the plunge into freelance, I would say it largely depends on how confident you feel, how much work you could potentially line up, and what your current situation is. It is wise to save up a few months worth of expenses while working freelance gigs on the side before quitting your day job. That said, I quit my day job because I was making more doing freelance than I was there and it was actually costing me money, in a sense, to work a job I didn't like for less.

I would suggest finishing your track, then doing the Starting a Business track, which is short and only has two courses, <a href="http://teamtreehouse.com/library/how-to-start-a-business">How to Start a Business</a> and <a href="">How to Market Your Business</a>. After that I'd do the <a href="http://teamtreehouse.com/library/how-to-freelance">How to Freelance</a> course, the <a href="http://teamtreehouse.com/library/how-to-run-a-web-design-business">How to Run a Web Design Business</a> course, and the <a href="http://teamtreehouse.com/library/how-to-write-a-business-plan">How to Write a Business Plan</a> course.

Good luck!
