Stress
Web design is not stressful. It's generally a nine-to-five job where you sit down at your computer, do your thing, and then go home to watch TV. Sure, you have to deal with the demands and requirements of the client you're designing a website for, but if you really wanted to, you could handle your customers from the safety and comfort of your own sofa or even a beach in the Bahamas, so long as you had access to the Internet.
