Unfortunately, Tang, a historian now, was not born in Xinjiang in the first century A.D., and can see the blending and glory of many ancient cultures. Hannah is eager to be born in the future and see a more interesting and useful life. But all we can grasp is now. Indeed, yesterday's beautiful flowers have become the past; Tomorrow, no matter how brilliant the sun is, it is illusory after all. It's just now firmly in our hands. Seize the present and don't dream about the future. Always think about the beauty of tomorrow, and the present time will pass in vain. Grasp the present, don't dwell on the past, always remember everything in the past, and your limited energy will be wasted. Grasp the present, we must cherish the time, and never let a minute slip away from our hands in vain. Lu Xun spent his coffee time reading, while Franklin thought that time was the substance of life. "An inch of time is an inch of gold, and a thousand dollars can't buy an inch of time." "Black hair doesn't know how to study early, but a bald head regrets studying late." Numerous vivid examples show that only by grasping the present can we create value. Seize the moment and act immediately. Heart is not as good as action, only action can make the present create value. Life is not a dream of waiting for a rabbit, nor is it an indulgence of tinkering, nor is it a regret of not being able to return to the past. Only action can determine the value of life. Life is not wandering, life is not waiting, and the best time in life is this precious moment. Only by grasping the present can we have and win the future. People who ignore the future will be abandoned.
