Almost always, not much is needed for a big decision. But it is necessary to make it and stick to it; it is necessary to honor it. The greatest effort, therefore, is subsequent, and involves converting a state of mind into practice, transmuting an impression into value. This cannot be done without an effective inner change: it is then easy to see that the great decision transforms, and is great because of the lasting effect that follows it and does not allow itself to be corrupted.
