Rushing is focusing on the next moment while ignoring this moment. This is why we make so many errors and mistakes when we rush. You’re stressed out by a distraction of choice.
It’s also why we can’t slow down. How can we slow down when we don’t rest on each moment? We have the next moment, the next worry, the next step, or the next problem to deal with instead.
If you hook a fish on your line and rush to reel him in, you put your line under max stress and it breaks. You catch the fish by letting out some line and being patient. Take it moment by moment rather than thinking only of the moment he is finally in your boat.
