When you start a new thing it's easier to remember that you're a beginner.
You're meant to be bad at this.
You're a beginner.
Similarly, when you've been doing something a while, you forget that you're still a beginner. You stop taking as much care and paying as much attention.
You "know what you're doing." Maybe you do.
And yet, you're still a beginner.
For the next few minutes in whatever you're doing, simply begin again.
Begin again as if you're doing this for the first time. Take as much care and expect little.
See what happens if you anticipate the result a little less.
