Walking a hundred miles, halfway is at ninety miles.

After walking 90 miles out of 100, you’re only halfway there.
The last half depends on your quality, foundation, background, and character.
If many friends fall along the way, you must be the last one standing.

No matter how certain or great an opportunity is, it’s never worth using up all your bullets, or even most of them. What we need to do is survive—the same holds true in real life.
