If you have made mistakes, even serious ones, there is always another chance for you. What we call failure is not the falling down but the staying down.
Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day; begin it well and serenely and with too high a spirit to be encumbered with your old nonsense.
When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.
What I must do first of all is be faithful. If I believe that the first commandment is to love God with my whole heart, mind, and soul, then I should at least be able to spend one hour a day with nobody else but God. The question as to whether it is helpful, useful, practical, or fruitful is completely irrelevant, since the only reason to love is love itself. Everything else is secondary.
