Any effort that has self-glorification as its final endpoint is bound to end in disaster.

It made the kids at camp much more enthusiastic and cooperative when they had ego goals to fulfill, I'm sure, but ultimately that kind of motivation is destructive. Any effort that has self-glorification as its final endpoint is bound to end in disaster. Now we're paying the price. When you try to climb a mountain to prove how big you are, you almost never make it. And even if you do it's a hollow victory. In order to sustain victory you have to prove yourself again and again in some other way, and again and again and again, driven forever to fill a false image, haunted by the fear that the image is not true and someone will find out. That's never the way.

You may be disappointed if you fail, but you will be doomed if you don’t try.

If you don't pay the price for success, you'll pay the price for failure.

...if we never try, we shall never succeed.

The reward may be uncertain, but our doom is inevitable unless we try.

It is true that I might stumble for trying to do too much too soon, but it is also certain that I will never succeed if I hope for too little, or out of fear of failing start not at all.

If you stake your hopes for a breakthrough on trying harder than ever, you may kill your chances for success.

You may be disappointed if you fail, but you will be doomed if you don’t try. – Beverley Sills

Those who are attached only to the result of their effort will not have any chance to appreciate it, because the result will never come.

If at first you don't succeed then skydiving definitely isn't for you.

When one tries to rise above Nature one is liable to fall below it.

If we don't succeed, we run the risk of failure.B

This forms the nub of a dilemna that every Everest climber eventually comes up against: in order to succeed you must be exceedingly driven, but if you're too driven you're likely to die.
