He Yi's speech mentioned that courage is very important.

Everyone knows that the courage to set out at any time is crucial; on the road, you will definitely see vast scenery, brilliant colors, different people, and novel travel experiences.
If exploring a career is also compared to a kind of departure, then courage is equally essential. This must be a kind of betting courage—you don't know what you will learn, what problems you will solve, or what achievements you will gain. Everything is unknown, but the unknown itself also represents some form of knowledge because you will definitely learn something, acquire some skills, and obtain some things.
This should be the charm of the unknown—what the unknown represents is knowledge, and what awaits is the realization at certain moments in the future.
Place your bets, young man. Courage is very important; the courage to bet is very important. Even if you pass through dark tunnels, silent nights, or even lifeless no-man's lands, with the road ahead vast and uncertain, only a heart full of passion and courage will see you through.
