To be strong is worth your life, to be contempt is worth a lifetime. To have a good attitude is a guide to life, as a train track is a foundation for the train

A smile shouldn't be kept inside, otherwise how will anyone see your light. To be angry is sometimes right towards indignations, but for at least your own sake, don't hold a grudge, or you may say something to put your foot in your mouth.

Be a friend when all possible, then someday when you grow old you may still have some old friends from way, way back. Never think that you know everything, for someone may test you, and exspect a correct answer every time.
