[irrational]

That's the trouble, everyone is different. My commute is only 20 minutes total every day (30 minutes if I ride my bike). I get 36 days of vacation every year (and a 6 week sabbatical every 5 years), plus from memorial day to labor day we only work until noon on Fridays.

5840 hours of waking time a year.

1845 hours of work time (217 working days * 8.5 hours; 1590 hours in a sabbatical year).

3995 hours left over to potentially do whatever I want.
