“I, not events, have the power to make me happy or unhappy today. I can choose which it shall be. Yesterday is dead, tomorrow hasn't arrived yet. I have just one day, today, and I'm going to be happy in it.”

“Each morning when I open my eyes I say to myself: I, not events, have the power to make me happy or unhappy today.”

“Yesterday is but a dream,
Tomorrow is only a vision.
But today well lived makes every yesterday a dream of happiness, and every tomorrow a vision of hope.”

“Today's happy face, today's sad face.
Yesterday, a weak self, tomorrow, a strong self.
If it's you, who are you showing it to?
If it's I, whom should I show it to?”

“Happy the man, and happy he alone,
He who can call today his own;
He who, secure within, can say,
Tomorrow, do thy worst, for I have lived today.”

“If in your own experience you haven't yet learned the truth of the deception of feelings, then you just have to go on believing and thinking, having faith in the past and hope in the future, being happy today and unhappy tomorrow, but never being in command of your own life for long.”

“I am not afraid of tomorrow
for I have seen yesterday
and I love today”

“The advance of regret can be so gradual that it is impossible to say "yesterday I was happy, today I am not.”

“I am in yesterday, today. And tomorrow? In tomorrow I was.”

“I am tomorrow, or some future day, what I establish today. I am today what I established yesterday or some previous day.”
