The things we procrastinate about, the things we want to get done with and out of our lives as quickly as possible, actually end up staying IN our lives the longest when we procrastinate.
We think, erroneously, that by delaying them, we'll spend the least amount of time possible with them. But in reality, they are with us the longest. Because every day we put them off becomes another day they're hanging around, nagging at us and reminding us of what we're NOT doing.
Do you want to get unpleasant or "not fun" things off your list or out of your way? Do them first.
