I design websites for a living. The one you're looking at now is only one of hundreds I've created over the years.

Nowadays, my job is pretty diverse - the way it is for most freelance webdesigners. It mostly consists of:
Work can be difficult and stressful at times, but I wouldn't trade it for the world.
I use Adobe Photoshop to create all my initial designs, and Coda to translate the design into a website. Yes, I hand-code, always have. You might say I can be a bit of a control freak at times. :)
