Work is important, but you can also be successful at building a family, having great friends, serving in the community, becoming physically fit, and so on. True success is only achieved when you're successful in all the areas that matter to you, not just your career.

1. Principle #1 — Recognize success is multi-dimensional. 

Work - life balance is not a myth. It can be achieved, but be aware it's dynamic rather than static. To achieve it, you're going to have to make ongoing adjustments and fine tuning. Weigh the domains of your life and give the right weighting to all the different domains.
