There are only two kinds of people in universities, one is scum and the other is talent.
Many people think it's enough to go to college, so they give up their studies and pursue those meaningless and boring things. The most important thing in a university is to study, but not just to study. There are many other important things, and there are many things that you need to exercise.
Of course, it is also good to find a good partner to work together, often with half the effort.
What your teacher said is a bit unrealistic, but he lied in good faith at that time, just hoping that you can study hard and have a good future.
Of course, not being admitted to college doesn't mean you won't succeed.
The future belongs to you. It is in your own hands. Work hard for your family, friends and loved ones. Always full of passion and vitality for life! I believe you will succeed!
Go, go, go.
