I use google Calendar because I can set it to send me email reminders.
Also, I print the month's calendar for a copy on my desk.
To download go to google.
Then I print a weekly schedule that I created from a spreadsheet. It has the usual things I do like exercise, take trash to the dump, check when bills are due, etc. I pencil in appointments and other one time events.
I know it's sort of obsessive/compulsive but at least I don't schedule the usual things I do; like when to shave, get dressed, have a snack or go to the bathroom. That would really be strange.
If trying programs for a lists of projects, a to-do list, a calendar and a schedule help reduce my fear of losing control, then I'll just have to do it.
For my routine I use:
Google Monthly Calendar with email reminders and I print a copy for my desk.
My printed schedule for the week which I made from a spreadsheet program.
Wunderlist for projects with sub-tasks I can transfer to my to-do list when ready.
Do it (Tomorrow) to-do list
Not 100% but good for me. Each person has to do what they find best.
I make sure to allow for unplanned spontaneous events by leaving plenty of slack time (about 50%) and flexibility. This allows for time to do nothing, take a nap, whatever I like at the moment.
