Yup. I have meetings at 8AM. If I had to do them in the office, I'll have to be up at 6AM to get ready and leave to be able to get to the office in time. If I do it at home, I wake up at 7:50, which gives me almost 2 hours of extra sleep.

If I leave the office at 5PM, I'll get home around 6PM. At home, I can log off as soon as the clock strikes 5, and now I have an extra hour of time to do whatever.

That adds up to around 3 hours a day that I save from not commuting to an office.
