"Economics is a day-to-day practice and is an easy endeavor made difficult for study reasons", he usually said. Watching the video to the end, I asked myself, "If I had the opportunity to go back in time would I pick another course to study? " And the answer was ..." No". And if I have the opportunity to advise any high school student about courses to choose... I'd say "Economics". The more people learn about even basic economics, the better the economy of countries.
So, if you had the opportunity to advise people about courses to choose In University, what would it be and why?
What the speaker you heard talking about economics said is his assessment, and we don't have the same assessment because we have our own assessment of something.
Also, the economic course is good; it helps a lot in business in reality. That's why there is an economist in every country because it helps a lot in reality. So I doubt that you made a mistake in your choice of economics course. Keep it up; don't stop.
