FDR spoke these words at Ogelthorpe University in 1932. Then, and now, I believe these words hold true.

And while the words are in reference to our country, I believe the idea could be applied to most things in life.

The country needs and, unless I mistake its temper, the country demands bold, persistent experimentation. It is common sense to take a method and try it: If it fails, admit it frankly and try another. But above all, try something.

…

We need enthusiasm, imagination and the ability to face facts, even unpleasant ones, bravely. We need to correct, by drastic means if necessary, the faults in our economic system from which we now suffer.
