Always remember that you belong to no one, and no one belongs to you

Even as bad actors cannot sing alone, but only in chorus: so some cannot walk alone. Man, if thou art aught, strive to walk alone and hold converse with thyself, instead of skulking in the chorus! at length think; look around thee; bestir thyself, that thou mayest know who thou art

Peace does not mean to be in a place where there is no noise, trouble, or hard work. Peace means to be in the midst of all those things and still be calm in your heart.

~Unknown

Of the five elements, none is always predominant;
of the four seasons, none lasts forever

of the days, some are long and some short, and 

the moon waxes and wanes - Sun Tzu
