William James is known as the father of American psychology. He once said:
“Everybody should do at least two things each day that he hates to do, just for practice.”
I call this mental cross-training.
There will always be things you dislike doing–laundry, homework, making sales calls, practicing, or eating healthy, for instance. But what if we didn’t feel like doing these things and did them anyway? How would that make us feel? I would guess that it would make us feel pretty good; it would make us feel proud. That would give us confidence. And it would give us momentum. That’s part of mental toughness.
Winners do what losers don’t feel like doing.
In other words…
You have to get comfortable being uncomfortable.
