So many people look on with envy, but in reality, very few can persist for 20 years. Most people, even if they start, probably can't stick it out and will get off midway. Instead of envying others, it's better to improve yourself. After all, when an opportunity comes, without the corresponding ability, you can only miss it. Choice is important, effort is important, persistence is also very important. If you achieve all of these, success is only natural.
