Whiloe work “forces” you to get up in the morning....if you do not have a reason to get up in the morning when you retire, your life will very quickly begin to suck!
Take your time "despacio" if you get all the stuff completed in a few weeks you will be board in a month.
If you do everything today you will have nothing to do tomorrow.
Relax, you now have the time to do things the right way and not the just get it done way.
It took me all of 15 minuets to settle into retirement. Above all enjoy your retirement you earned it.
I almost forgot at least 1.5 hours on FR daily is a requirement for long life.
