This is a topic widely discussed on the internet, and you will likely see STEM sciences as a popular answer. Common sense also tells us technology is never "going out" of style, and people will always need doctors, lawyers, and tax accountants. Ability to sell anything is critical, as is general leadership. It really depends on what you are good at naturally.
The other piece is the future is not predictive; no one has a crystal ball to say what the next best industry, or consumer good will be. But we do know companies are going global (read: learn at least foreign language, and study abroad), media is digital in nature, and environmentally sensitive products and services get lots of press now a days.
How about you pick up the Wall Street Journal, USA Today and one big foreign newspaper (in your native tongue), and read these for about 2 weeks consistently. What kinds of companies do you see in the news regularly? What company stocks are outperforming others (anotherwords learn how to read the investment section of the paper). This will give you clues as to what the future may hold.
