1. I started doing web design and development at age 11. Was just a football playin computer junkie. yeah, imagine that. Learned HTML, and Photoshop.. just have done crazy since then. Ive ran three web development companies and have done work for some fairly large companies.
2. Good points: creativity, difference in work (no project is ever the same), awesome pay
Bad Points: headaches, lack of free time, idiots for clients (mostly)
3. My average is about $34,000 / year.
