Hell no, the amount of problems caused by people half-assing everything they do is enormous. The write fails to take onto account that the question of just how much effort us required is often highly subjective. It's more a matter of values than anything objective.

How well do you care about something to figure out just how well you could possibly do, when doing better matters in outcomes?

Taking the advice of TFA to heart confirms an attitude of never really caring to do anything well.

Of course, for many things, it is probably not productive to spend too much effort on it.
