Stop working so hard
On this theme, I've found having kids has actually helped me be more productive. I don't have the opportunity to work crazy hours. I know I can't catch up in the evening so I have to make every day count. Because my hours are limited to a standard working day I never burn-out, and I'm motivated and ready to go each and every day.<p>When they were really young it was rough (no sleep, etc.) but now they're a bit older it generally works out well. (Modulo illness. They are both currently coming down with something and it's going to wipe out at least two working days.)
