Here's help for those who don't have enough time for exercise or family

Columnist Penelope Trunk (and author of the "Brazen Careerist") writes in her blog about different ways to control the amount of time you spend at the office thereby freeing up the time you need for family, exercise, hobbies, lifelong learning, etc., etc.

Penelope's tips for managing your hours include:

Concentrate on quality of work over quantity. People don’t lose a job for not working unpaid overtime, they lose a job for not performing well at the most important times.

Know the goals of your job. Judge if your work is high quality by what people need from you and how they measure success.

Find the back door. Figure out what criteria people use for promotion. It is never only how many hours you work.

Refuse bad assignments. Figure out what matters, and spend your time on that.

Say no. Prioritizing is a way to help your company, your boss, and yourself.

Go public. Tell people about your schedule ahead of time.

Find a silent mentor. Look for someone who is respected but does not work insane hours.

Know your boss’s goals. Because if you worm your way out of work that doesn’t matter to her, so that you can do work that does matter to her, she is more likely to back you up.

Take control of what you can. Refuse meetings after 4:30 p.m. and you are less likely to miss dinner at home.

Know your own boundaries. Try getting home by 7 p.m., not working weekends, or leaving for two hours in the middle of the day to lift weights.

Create something important outside of work. If you don’t create a life outside of work that is joyful and engaging then you won’t feel a huge need to leave work.

Be brave. Brave people can say no when someone is pushing hard, and brave people can go home when other people are working late.

The key message is that you must take responsibility for the hours you spend at the office. Don't blame your boss, don't be a time victim, and don't romanticize workaholicism. Click to Penelope's blog post for elaboration on all of the tips above.

Of course some jobs are simply incompatible with having a personal life. For those you may want to consider a job change or even a change of careers.
