If you’ve got a big block of free time, the best way to put that to use is to relax, have fun, decompress from a stressful day, or spend time with a loved one. But if you’ve just got a little chunk — say 5 or 10 minutes — there’s no time to do any of the fun stuff.
Put those little chunks of time to their most productive use.
Everyone works differently, so the best use of your free time really depends on you, your working style, and what’s on your to-do list. But it’s handy to have a list like this in order to quickly find a way to put that little spare time to work instantly, without any thought. Use the following list as a way to spark ideas for what you can do in a short amount of time.
