The great things you intend to do some time must have a beginning if they are ever to be done, so begin something worthwhile today.
There are many fine things which you mean to do some day, under what you think will be more favorable circumstances. But the only time that is yours is the present.
Make your judgment trustworthy by trusting it. Cultivate regular periods of silence and meditation. The best time to build judgment is in solitude, when you can think out things for yourself without the probability of interruption.
