The tides advance;the tides recede. Winter goes and summer comes. Summer wanes and the cold increases. The sun rises ;the sun sets. The moon is full ;the moon is black. The birds arrive! the birds depart. Flowers bloom ;flowers fade. Seeds are sown;harvests are reaped. All nature is a circle of moods and I am a part of nature and so, like the tides, my moods will rise;my moods will fall.

It is one of nature's tricks, never know the reason why they will change, that each day I am awaken with moods that are different from yesterday.Yesterday's joy will become today's sadness;yet today's sadness will grow into tomorrow's joy. It seems that there have got a wheel inside me,which  will constantly turning from sadness to joy, from exultation to depression,from happiness to melancholy. Like the flowers，today's full bloom  will fade and withers into despondency, yet I still remember that as today' s dead flower can carries the seed of tomorrow's bloom. Does today's sadness carry the seed of tomorrow' s joy? I guess, that should be.

And how will I master my emotions so that every day is a happy  and a productive day? I will learn this secret of the ages: Weak is he who permits his thoughts to control his actions;strong is he who forces his actions to control his thoughts. Each day, when I am awake, I will follow this plan of battle before I am captured by the forces of sadness, self-pity and failure.For if my mood isn't right, the day will be a failure. Trees and plants depend on the weather to flourish, then I have to find my right weather to depend on.

 If I am overconfident, I will recall my failures.

 If I am overindulged, I will think of my past hunger.

 If I feel complacency, I will remember my competition.

 If I enjoy moments of greatness, I will remember moments of shame.

 If I feel I am powerful ,I will warn myself that I am not.

 If I attain great wealth ,I will remember that there more people wealther than me.

 If I feel proud, I will remember the moment when I am  helpless.

If I feel myself skillful, I will think the one who is better than me.

 Henceforth I will recognize and identify the mystery of moods in all mankind. From this moment, I am prepared to control whatever personality weaknesses in me everyday. I will master my moods through positive action, and when I master my moods I will control my destiny. I will become master of myself. I will become great.
