You can’t keep working at the same pace day in, day out. But you don’t have to stop either. You can just drop a gear.
Maybe you’re feeling unwell. Maybe you’re stuck. Maybe you don’t have the time.
Drop a gear, or two, and you still make progress. You’re pace will drop but you haven’t stopped, you’re still moving forward.
Don’t let the day defeat you. Drop a gear and get over that hill.
