Life begins at the end of your comfort zone
If you always put limits on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus; and you must not stay there, you must go beyond them.
In order to achieve something you have never had before, you must do something you have never done before.
Impossible is just a big word thrown around by small men who find it easier to live in the world they’ve been given than to explore the power they have to change it. Impossible is not a fact. It’s an opinion. Impossible is not a declaration. It’s a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.
The secret of getting ahead is getting started.
Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something will take it’s place. If I quit, however, it lasts forever…
You’ve only got three choices in life — give up, give in, or give it all you’ve got.
Strength does not come from physical capacity. It comes from an indomitable will.
A ship in harbor is safe, but that is not what ships are built for.
