Enjoy present pleasures in such a way as not to injure future ones.

The past the present and the future are really one: they are today.

We must respect the past and mistrust the present if we wish to provide for the safety of the future.

The future is no more uncertain than the present.

Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs the future for which I have really worked is mine.

The essence of optimism is that it takes no account of the present but it is a source of inspiration of vitality and hope where others have resigned it enables a man to hold his head high to claim the future for himself and not to abandon it to his enemy.

The reason people find it so hard to be happy is that they always see the past better than it was the present worse than it is and the future less resolved than it will be.

Happy is the person who knows what to remember of the past what to enjoy in the present and what to plan for in the future.

Never let the future disturb you. You will meet it if you have to with the same weapons of reason which today arm you against the present.

There's no present. There's only the immediate future and the recent past.
