some Nice quote's :
Now I see the secret of making the best person: it is to grow in the open air and to eat and sleep with the earth.
Think in the morning. Act in the noon. Eat in the evening. Sleep in the night.
If you cannot sleep,then getup and do something instead of lying there worrying.It is the worry that gets you,not the lack of sleep.
