Generalist Education versus Specialist Education (long sorry)???

I really don't buy into the whole "specialization," aspect of college/life. Yes, it makes us very proficient in a certain field (more than a generalist usually) but doesn't it also make it difficult for us to think in different ways, especially in the later years?

I'm currently an Economics major in college but I have:

- Taken all of the hardest math classes my school has to offer (It's a stem school)

- Am taking computer science classes currently (coding seems to be more important every year)

- Am trying to take the hardest chemistry and organic chemistry classes my school has to offer (with MUCH criticism at my back from friends, family and academic advisers).

Will I regret these decisions?

I know I can not, but I want to learn everything and understand everything.

Does anyone feel the same way?
