I don’t know if this is actually a productivity tip or not. It might actually waste more time than anything else, but I feel like it is a good thing.
Do you have a huge collection of pennies that are building up? My wife and I have a metal box full of our loose change. We run most of our expenses through our credit cards, but we still end up with a bunch of coins. I have found a use for pennies.
The toll roads in Chicago take pennies. I don’t know if this works in many other major areas or not. There is something deeply satisfying about throwing 80 pennies into the machine to pay for your toll. Of course you probably don’t want to sit at the toll booth counting out 80 pennies. If you have a passenger in the car, that can be their job. Otherwise, you can count out the pennies into appropriate quantities when you are at home and keep them in the car for use while you are driving.
Let me reiterate that this is unlikely to directly make you more productive, but for me it provides me with a deep inner happiness and when I’m happy, I am more productive.
