Taking a step back, breathing in, and looking at your projects from a distance is necessary to remain sane when you have projects. Else you dive nose-in, and you can only see that, and then when you achieve it, you realize that you haven't done nearly as much for yourself as you have done for the project, it takes away a lot from the feeling of achievement. Plus if you are not healthy enough to enjoy it, then odds are you will not be able to do anything more for the project and will go straight into a burn-out you can't come back from.

Have Fun!
