"When you surrender to what is and so become fully present, the past ceases to have any power. You do not need it anymore. Presence is the key. Now is the key." 

-Eckhart Tolle

“We are not held back by the love we didn’t receive in the past, but by the love we’re not extending in the present.” 
-Marianne Williamson

"Enlightenment comes up first and it means to just be present. If you want to be what you want to be, be present. Just stand up straight, with stability, and then simultaneously your effort turns into practice. Then from this practice the teaching will come up later." 
-Dainin Katagiri

"There is no goal of life. Life itself is its goal. It is not moving towards some target. It is herenow, it has no future. Life is always in the present. But the mind cannot live in the present: mind dies in the present." 
-Osho

"Your present circumstances don't determine where you can go; they merely determine where you start." 
-Nido Qubein

"A fool is one who goes on trusting;
a fool is one who goes on trusting against all his experience. You deceive him, and he trusts you;
and you deceive him again, and he trusts you;
and you deceive him again, and he trusts you.
Then you will say that he is a fool, he does not learn. His trust is tremendous; his trust is so pure that nobody can corrupt it. Be a fool in the Taoist sense, in the Zen sense. Don't try to create a wall of knowledge around you. Whatsoever experience comes to you, let it happen, and then go on dropping it. Go on cleaning your mind continuously; go on dying to the past so you remain in the present here-now, as if just born, just a babe." 

-Osho

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

-Marcus Aurelius Antoninus Augustus

"Do you have the patience to wait
till your mud settles and the water is clear?

Can you remain unmoving
till the right action arises by itself?

The Master doesn't seek fulfillment,
but not seeking, not expecting,
is present, and can welcome all things."
-Lao Tzu
