What does it mean to aim high, but you can't understand yourself unless you are lucky?

1, "If you have ambition, you can't walk without luck", which means that even if you have ambition and ideal to reach the sky, if you lack luck, you can't achieve your goals by yourself.

2. The original text is from Lv Mengzheng's Broken Kiln Fu in the Northern Song Dynasty. Excerpts from the original text are as follows: there are unexpected events in the sky, and people have misfortune and happiness. Scolopes has a hundred feet and can't walk like a snake; The rooster has two wings, but he can't fly over the crow. A horse has a journey of a thousand miles, and it can't be done without riding it; People are ambitious, but they can't be self-sufficient unless they are lucky.

The situation in the sky is unpredictable, and disasters and happy events in one's life will come at any time. The centipede has many feet, but it still doesn't walk as fast as the snake; Although domestic chickens have big wings, they can't fly like birds. Although a horse can go far, it can't walk without a rider. A person has the ambition and ideal to reach the sky. Without luck, it is impossible to achieve your goal on your own.
