You can't change your appearance, but you can smile

You can't change the length of life, but you can expand its width.

You can't do everything smoothly, but you can try your best.

you can't change the environment, but you can change yourself;

you can't change the facts, but you can change your attitude.

you can't change the past, but you can change the present;

you can't control others, but you can control yourself;

you can't predict tomorrow, but you can grasp today;

you can't do everything smoothly, but you can do everything with all your heart;

You can't control the weather, but you can change your mood.

You can't choose your appearance, but you can smile.

you can't extend the length of your life, but you can decide the width of your life.
