I feel most productive in the mornings, starting at about 7 AM and going until 2 PM. After breakfast and coffee, because I get up at 5 AM to capture this productive time.

I get a lot done in the morning. At work, I get lectures written and assignments graded in the morning when I get here at 7:30 AM. Today I’m getting my blog written because I didn’t write it the day before. That’s how productive I am in the morning — I almost get ahead of myself.
I’m not as productive in the afternoon, but often work to keep from getting bored. By 4:30 PM, though, I’m ready for a rest. Dinner, then vegetative time. Then bed by 8. I have a boring night life, but it works for me because it keeps me productive in the morning.
Off to go work now.
