Living in the moment means letting go of the past and not waiting for the future. It means living your life consciously, aware that each moment you breathe is a gift.
It is our own mental attitude which makes the world what it is for us. Our thought make things beautiful, our thoughts make things ugly. The whole world is in our own minds. Learn to see things in the proper light.
In the sweetness of friendship let there be laughter, and sharing of pleasures. For in the dew of little things the heart finds its morning and is refreshed.
If you have done the best you can do and if you have gotten all you could extract from something, you have given all you had to give, then the time has come when you can do no more than say thank you and move on.
