Our greatest weakness lies in giving up.
The most certain way to succeed
is always to try just one more time.
- Thomas A. Edison
Being defeated is often a temporary condition.
Giving up is what makes it permanent.
- Marilyn vos Savant
Our greatest glory is not in never falling,
but in rising every time we fall.
If you run into a wall, don't turn around and give up.
Figure out how to climb it, go through it, or work around it.
- Michael Jordan
