Fear is the workout we give ourselves imagining what will happen if things don't work out. . . . Worry is our effort to imagine every possible way to avoid the outcome that is causing us fear, and failing that, to survive the thing that we fear if it comes to fruition.

We are too focused on avoiding criticism and not enough on making a difference.

The problem with holding a grudge is that your hands are then too full to hold onto anything else. It might be the competition or a technology or the lousy things that someone did a decade ago. None of it is going to get better as a result of revisiting the grudge.

Every single important thing we do is something we didn't use to be good at, and in fact, might be something we used to fear.

It's almost impossible to have fun playing ping pong with someone who doesn't care, won't try or isn't any good.

If you don't know how it works, find out. If you're not sure if it will work, try it. If it doesn't make sense, play with it until it does. If it's not broken, break it. If it might not be true, find out.

The resistance is the voice in your head telling you to use bullets in your PowerPoint slides...It’s the voice that tells you to leave controversial ideas out of the paper you’re writing, because the teacher won’t like them. The resistance pushes relentlessly for you to fit in.
