Success needs no explanation. Failure does not have one that matters.

They who have conquered doubt and fear have conquered failure.

Success and failure are both part of life. Both are not permanent.

Success consists of going from failure to failure without loss of enthusiasm.

Remember that failure is an event, not a person.

There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.

Outward failure may be a manifested variant of inward success.

Success is not final, failure is not fatal: it is the courage to continue that counts.

If you're not failing every now and again, it's a sign you're not doing anything very innovative.

We may be personally defeated, but our principles never!
