Dedication to DIY and programming

While browsing my favorite DIY web sites I found an interesting article about the common mistakes that need to be avoided when working as a freelancer. You can see the original article here : Common Mistakes to Avoid When Freelancing .
Besides those 3 reasons, I can add ( after a lot of RentACoder.com experience) :

• try not to take too many jobs at once
• remember that when you choose to be a freelancer you choose your own projects, this can be a real disadvantage because you do only projects that you like and on more than 50% cases, freelancers ignore new technologies
• you don’t have a fixed income
