Don't let yourself suffer needlessly, find a need to suffer.

I will stop at nothing to reach my objective, but only because my brakes are defective.

How can I fail when I have no purpose?

It's hard letting go of the past, when there are no firm handholds in the future.

If you can't learn to do it well, learn to enjoy doing it badly.

It's hopeless! Tomorrow there'll be even more books I should have read than there are today.

Even if you're not enjoying the flight, it's futile to threaten to get out and walk.
