The telltale signs of rushing – those rapid heartbeats, those frenetic movements of your limbs, the way your eyes will dart from focus point to focus point. You have a lot to do today! You need to hurry!
No, you need to do the exact opposite. Rushing doesn’t get you speed, it gets you mistakes. You can only achieve speed when you have a single task, a central focus. If you’re driving across the country, then an increase from 55 MPH to 65 MPH is a significant saving in your overall journey time. If you’re staying local and visiting 6 different stores for a bunch of errands today, then going from 35 MPH to 45 MPH won’t gain you anything but an increased risk of an accident. You aren’t on any one road long enough for the increase to matter, and any tiny gains you make will be lost at a single red light or long line in a store.
Things take as long as they take, plus any mistakes you make. The trick isn’t to rush; it’s not to skid.
