First, make your to-do list, but don’t include everything under the sun. Start out with about 9 things that you can do (or make progress on) in half an hour or less.
Find a random number generator, roll some dice, or do whatever you like to do for getting random numbers. This way you can’t pick favorites on your list and forget to do the other things.
Get your first random number. Good, it’s the easy one. Do that thing.
Next random number. Ugh, it’s the horrible terrible thing. How about we do this thing for 10 minutes? Set a timer. Do the thing for 10 minutes. If it’s still horrible, abandon it. If not, keep going.
And so on. It’s not rocket science, but it fills the need of a blog post for today, and even though it isn’t on the list, it’s like the secret number 10 entry.
