Just to be different, here's my semi-retirement day:
8:30am - 10:30am
Wake up, shower, shave, have breakfast, watch the morning news, do various things around the house, play with my kid, online browsing.
10:30am - 12:30pm
Work
12:30pm - 3:00pm
Lunch, take a power nap, go shopping for fresh groceries for the evening dinner, do whatever comes to mind, or just sit outside in my lawnchair and think.
3:00pm - 5:00pm
Work
5:00pm - Midnight
Cook, have dinner, go out with wife and/or play a sport my my kid, watch TV, read, listen to music, plan next vacation, do any of my hobbies, go online, visit friends or family, wash the car, cultivate the vegetable garden, fix things around the house, or whatever else I feel like doing.
