I find I have limited bandwidth for coding. In my last job, this capacity was completely used. I put my energy and my ideas into my job and absolutely nothing was left for building on the side.

My current job is still technical, but I'm not working as a coder. As such, I have a lot of energy to put into a project. In fact, working on the project is one of the things I look forward to when I get home.

Something to keep in mind when looking at a job. How much of your personal capacity will be left when the day is over?
