My personal opinion is that programmers

The reason is ①: Being a programmer has many opportunities for exercise.

②: Being a programmer is more realistic and useful. You can gradually turn your theory into practical application ability. I believe that if I give you a project to do now, you will also hit a wall. This is natural.

Being a lecturer is very demanding. I have no experience yet. Personally, I think we can do it?

③: I like challenges. Being a programmer, in a word, is cool.
