If you do not try, you will never know if you can succeed; if you lack confidence, then go and learn, for only through mastery can one achieve excellence. Bitterness is the essence of life, and exhaustion is its constant state. No matter how far you travel, how high you stand, or how much you gain, you cannot escape the entanglement of hardship and fatigue. Life is a process of endurance and pressure, driving us to forge ahead under weight and push ourselves forward through adversity. No matter where we are, we must learn to support ourselves, offering encouragement during failure and warmth during loneliness, striving to keep our souls light and our spirits buoyant. Maturity is facing trivialities with a smile. There are three things in life not to be squandered: health, wealth, and love; to squander them is to lose more than you gain. There are three things that cannot be held back: life, time, and love; trying to cling to them only makes them drift further away. And there are three things not to dwell upon: disasters, death, and love; to dwell on them brings only misery. "One cannot ride two horses at once; to mount one, you must let go of the other. Wise people set aside anything that distracts them." Our life and energy are finite; we should act like a magnifying glass, filtering out distractions and focusing all our passion and energy on our goals. The best state of mind is calmness and composure. If life is a drop of water, then desire is a rushing river. Can anyone win a race against infinite desire with a finite life? The bitterness of desire lies in either being unable to obtain or being unable to let go. Let things go naturally if they are not meant to be. Remember, greatness lies in tolerance, and strength lies in lack of desire.
