Jack,
Sleep in...maybe go out for breakfast. Drift on back home about mid-morning and check your email. Sit outside for a while and listen to the birds.
Have a nice lunch. Get a blanket and lay out in the back yard a while...hope for some white puffy clouds. Try to figure out what animal the cloud resembles, like you did when you were a kid. Wait...to be overtaken by a nap.
When you wake up refreshed, you might just want to think a bit about the project at hand. OK...enough thinking...go check email and help Mrs. Jack prepare dinner. Linger in soft conversation...stack the dishes, they can wait until...
Take an early evening walk, might need a light jacket. Come home and watch a little TV, then check email and turn in for the night.
Then, maybe, begin work on the next day...or maybe not.
Be certain that every day you do what you want to do; you've waited since third grade to have that luxury. If it's tearing into the project early tomorrow morning, that's fine...if it's not, that's fine.
Your friend in retirement,
Ray
PS - tomorrow I'll weld in the driver's side bulkhead/floor reinforcement brace, finish off the floor pan welds, and hang the driver's side rear suspension...or maybe not.
