All of old. Nothing else ever. Ever tried. Ever failed. No matter. Try again. Fail again. Fail better.

Go on failing. Go on. Only next time, try to fail better.

Ever tried. Ever failed. No matter. Try again. Fail again. Fail better.
—Samuel Beckett, Worstward Ho (1983)

Giving up is the only sure way to fail.

Few things are impossible to diligence and skill. Great works are performed not by strength, but by perseverance.

If you fell down yesterday, stand up today.
