Did you see how crazy my blog title sounds when you read it? It’s practically offensive. But we do this to ourselves all the time. The day doesn’t feel productive unless we’ve crammed in X number of things and gone as fast as we can to get them all done.
No!
We should measure success by whether or not we did the thing, not by how long it takes to do it or how difficult it is to do.
Measure yourself against who you were yesterday. Did you commit to and do your job today?
If the answer is yes, stop worrying about speed and difficultly. The job is done. You did your duty. You did well.
