I quite fancy being a travel writer. Do a bit of sight-seeing during the day, a nice meal in the evening and enjoy the seedy underbelly of the city at night. Write up the publishable bits the next day and move on.
Don't choose a boring profession or something you don't like then. I could never get sick of manipulating and breeding hundreds of plant species. It doesn't even have to be weed.
I have my dream job. 7am - Get up for a ****, shower and breakfast. Read for an hour. See the nippers off to school. 9am - Start working. Noon - Lunch, followed by an hour of reading. 1.30pm - Continue working. 3pm - Kids come home. Play, read and do homework with the kids. 8pm - Spend three hours with the missus. 11pm - Back to work. 2am - Research and planning for the next day. 3am - Bed. Saturdays, Sundays, Mondays are always days off.
