EVERYONE has limitations. Everyone still has to sleep X hours per day. Spend X hours per day doing X. Kids or no, I can only squeeze out maybe 4 - 6 hours per day of solid coding before my brain quits on me. The rest of my working day is doing less taxing things which still need to be done as a freelancer.

Budgeting time is just like budgeting money. You just have to make sure you're spending it well. It's best to be diversified, so spend some of that working time on something which can bring in an alternative revenue stream. It may not pay off right away, but it could pay off huge in the end.
