Consider that there are 168 hours in a week, and even accounting for 8 hours of sleep a day that's 112, subtracting 40 for work and you get 72. Lets call it an hour commute each way, that brings it to 62.

So you actually have 62 hours of personal time every week to the 40 you spend at work. In other words, you could be getting 22 more hours of productive work done in your free time than you get done at work every week.

This suggests that it isn't really a time problem.
