Not knowing what post-secondary school you went to it's worth saying that not all universities and colleges are equal. Don't go to a bad school. Don't go to a mediocre school even.

"Attending a very elite school and choosing the right field often has a significant payoff. The best program anywhere in the United States is the computer science major at the California Institute of Technology. Graduates of this well-regarded program can expect an ROI of $4.41 million over the course of their careers. Not far behind is the finance major at the University of Pennsylvania’s famous Wharton School, where lifetime ROI is $4.35 million."
We can debate whether top schools actually teach any better or whether they're just skimming off top students out of high school, but there's a significant difference in groups outcomes between schools.
