If spending time with ones family is part of what it means to be a family, and when time/work pressures make it difficult to do so, I would say "accomplishment" is more than appropriate.

Raising an happy and healthy child is an accomplishment, and both parents need to be involved. Giving happiness to your family is an accomplishment, a much bigger one than "imagining" (because, lets get real, this is just a nice dream) futuristic trains travelling in a vacuum pipeline.

You don't have a family? Ok, spend all your time imagining nice stuff and give press releases about your imaginary stuff, but don't call it job, call it hobby. Are you still calling it a job? Then you shouldn't be spending so much time on it.
