If you've got a today, don't wear it tomorrow. Tomorrow never happens. It's all the same day.

The barrier to success is not something which exists in the real world; it is composed purely and simply of doubts about ability.

The struggle of today is not altogether for today - it is for a vast future also.

Our real problem, then, is not our strength today; it is rather the vital necessity of action today to ensure our strength tomorrow. What I have just said applies to our strength as a single country.

Any orderly balance-sheet of military strength must be in two parts. The first is the position as of today. The second is the position in the period ahead.

Doubts could be swept away only by deeds.
