Do you worry about trying to attain more work/life balance? It's often asked of me personally how I manage a family of six children including twins and triplets (not to mention three cats and two dogs that only I walk) while running my own business and traveling so much.
I believe the concept of balance is bologna. A pure fallacy.
The only thing you can do is free up some time from Peter to pay Paul so to speak. To do that, as time doesn't appear out of thin air, you have to be more effective and make harder choices about what you do with your time, in other words be more focused.
Effectiveness is doing what you chose to do better. Meaning quicker, smarter, faster. Choice means focusing. Focus your time and do the right activity for you personally.
This problem falls more often on women's shoulders. The reality is that one can't do it all or have it all. You cannot work fifty hours a week, bake your bread, raise happy children, be a sex goddess/god, keep a perfect house, do your own accounts, be an involved school / sport / community parent and get enough sleep. There are only 24 hours in a day no matter how great at multitasking you are.
