When I was a kid I remember I disliked practicing the piano.
Until I became friends with a person who loved to practice piano and did so for hours on end.
I realized practicing could be enjoyable, something I hadn't even considered before.
That's what I thought of when I read this Tony Robbins quote.
Our brains are designed to seek out pleasure and avoid pain.
We can put this knowledge to good use by associating the actions we want to keep doing with pleasure and the habits we don't want to keep, with pain in our minds.
