I am not dreaming This is a real day, a beautiful one. Do we want to return to the past and play hide-and-seek? We are here today, and we will be here tomorrow. This is true. Come, you are thirsty. We can walk together to the spring of fresh water.
Because I don't live in either my past or my future. I'm interested only in the present. If you can concentrate always on the present, you'll be a happy man... Life will be a party for you, a grand festival, because life is the moment we're living right now.

Look not mournfully into the past. It comes not back again. Wisely improve the present. It is thine. Go forth to meet the shadowy future, without fear.
The master said, 'Quietly to store up knowledge in my mind, to learn without flagging, to teach without growing weary, these present me with no difficulties.'
All human situations have their inconveniences. We feel those of the present but neither see nor feel those of the future; and hence we often make troublesome changes without amendment, and frequently for the worse.
