Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment.

"Don't think of what's past!" said she. "I am not going to think outside of now. Why should we! Who knows what tomorrow has in store? "

It is difficult to live in and enjoy the moment when you are thinking about the past or worrying about the future. You cannot change your past, but you can ruin the present by worrying about your future. Learn from the past, plan for the future. The more you live in and enjoy the present moment, the happier you will be.

forget the past, for it is gone from your domain! forget the future, for it is beyond your reach! control the present! Live supremely well now! This is the way of the wise...

If you want to be happy, do not dwell in the past, do not worry about the future, focus on living fully in the present.

Don’t think about the future. Just be here now.

Fear not for the future, weep not for the past

We must never get into the habit of being preoccupied with the future. There is no reason to do so; God is there.

Vive el presente, recuerda el pasado y no temas el futuro, porque no existe, ni existirá jamás. Sólo existe el ahora.

Shut out all of your past except that which will help you weather your tomorrows.

Live in the present, remember the past, and fear not the future, for it doesn't exist and never shall. There is only now.

Do not worry about tomorrow, for tomorrow will worry about itself..

Touch a button and hear, at every level of your life, the iron doors shutting out the Past the dead yesterdays. Touch another and shut off, with a metal curtain, the Future the unborn tomorrows. Then you are safe, safe for today! Shut off the past! Let the dead past bury its dead. Shut out the yesterdays which have lighted fools the way to dusty death. The load of tomorrow, added to that of yesterday, carried today, makes the strongest falter. Shut off the future as tightly as the past. The future is today. There is no tomorrow. The day of man's salvation is now. Waste of energy, mental distress, nervous worries dog the steps of a man who is anxious about the future. Shut close, then the great fore and aft bulkheads, and prepare to cultivate the habit of life of 'day-tight compartments.

I’ve learned not to worry about what might come next.
