Below is a great post by Jason Fried of 37Signals. He puts an important concept into simple words.
My biggest problem has been slowing down. I tend to work out too fast. Lift too fast, do crunches too fast, do pushups too fast, etc.
I haven’t been able to catch myself when I’m going too fast. I’m certainly capable of slowing down, and I fundamentally understand the benefits of slowing down, but I just couldn’t come up with something that pops in my head to encourage me to slow down when I find myself going too fast.
Then my trainer asked me what I would do if I had three darts, had already thrown two, and I only had one shot left at hitting the bullseye.
I told him
I’d slow down. I’d take a deep breath, measure the distance, mock a few practice throws back and forth, settle in, focus, and throw. I wouldn’t rush up there and just toss the thing.
And it clicked for me. When you really want to do something right, which is usually what you should be striving for, you tend to slow down.
Of course it’s all relative as some things are more important to get right than other things, and there’s often external context which may make slowing down impossible, but in general, given the opportunity, you’d slow down to get something right.
And while some things really do require split-second decision making, the worst thing to do is to invent artificial urgency and cheat yourself.
