He who believes needs no explanation.

Excuses are useless. Results are priceless.

For those who understand, no explanation is needed. For those who do not understand, no explanation is possible.

There is no substitute for victory.

To him who has had the experience no explanation is necessary, to him who has not, none is possible.” And

Never explain. Never complain.

There are no mistakes

Success doesn’t care which road you take to get to its doorstep.

Success is never accidental.

There is no point in using the word 'impossible' to describe something that has clearly happened.

There is no excuse for not trying.

Never apologize, never explain.

There is no failure except in no longer trying.

To one who has faith, no explanation is necessary. To one without faith, no explanation is possible.
