This is actually very sound advice - the "do what you love to do" part. My guess is that whatever unique qualities you have to offer this world they will come out regardless of the kind of education you choose. Twenty years ago I decided that even though I was probably leaning more towards CS that something more was neeeded, so I choose an education that combined CS and Business Administration.

My CS skills probably never got developed the way they might have been had I chosen to go the pure CS way, but since my interest was mostly there I made up for it in my own studies along the way. And having an understanding of business helped me work within the financial sector.

Overall I'd say this has worked out for me, but there has been times of frustration when I wondered if having a straight CS education might have been better for me. For a lot of years I was the business-oriented guy who tended to get the techie problems because they seemed to get solved when sent my way. Now, being older I find that I tend to leave the technical problems to younger programmers who like the challenge of doing the technical stuff for it's own sake, while focusing more on the business rules and how to best support the clients i work with in getting solutions that work at a low development cost.

So, I guess my point is that you should not be frightened about making choices because what you learn during your studies may come in handy at another time in your career, and what you don't learn during your studies you can always make up for later in life if your priorities change.
