Does anyone remember a teacher or teachers in high school telling them that what they're learning is somehow going to be important later in life so they had better learn it well and not to forget it?

I had a math teacher explain to me that learning Algebra is important and it will benefit me because I’m probably going to need to know it later on in life.

I’m now 41 years old and I can’t remember a single time, outside of high school, where Algebra has ever been significant in anything that I’ve done.
