I think energy would be the answer for many people. Seems easy to become demotivated from corporate work and let that leak into your side projects.

Not that I disagree with you. But I've run into the problem myself. I think what you state is probably the best option though. Just gotta get life in order enough to avoid the energy issue.

Energy or time. If you have a family you probably don't have time for side gigs
