First of all, no one is a real loser. You naturally have your reasons in this world, and you naturally have your uses. Don't think about meaningless things like being a waste. As for doing things and studying, everyone's qualifications are different. Some people have good qualifications, can do what they like and learn what they can. Some people have average qualifications, and it is difficult to do anything and know nothing. This is predestined. Although they can make some improvements through their efforts the day after tomorrow, they are limited after all, so there is no need to blame others.
For example, who do you want to study hard and work hard, will he become Einstein, Li Ka-shing and Ma Yun? It is out of the question. Don't say it's too high, just say that if you study hard, you will be the first in the school? You know, there is only one person who is the first in the school, and there must be more than one person who studies hard. To say the least, if you study hard, won't you be the last in the class? So if all of you really study hard, will the last one in the class disappear? That's absolutely impossible. A person will get the final result.
So I dare not step back and say that you are the worst one in the world. Don't compare yourself with others. Compare yourself with yourself yesterday. If you got a 1 yesterday and a 2 today, that's progress. It's good to have progress. If you can make progress by one point a year and live a long life, you will get full marks if you are still alive at the age of 100. Besides, it is impossible to really make such slow progress.
Some people are gifted, and the youngest is a genius. This little genius may not do much, only a small part of them do. Some people have average talent, but they have been working hard the day after tomorrow, and some people are late. Besides, some talents are also some talents. As long as you have confidence and make progress slowly, you will succeed one day.
