The supposedly obvious answer would be "be a psychologist". But actually, to become a psychologist, you have to get a graduate degree on top of your bachelor degree as well as complete additional training. Now, what can you do with any degree in psychology? Actually, any profession that entails understanding of people and personal interaction can make use of training in psychology. And there are quite a few. From any counseling to advertising to leadership positions. Psychological motivation of people can be incredibly complex. Further, training psychology requires you to understand experimental design and human performance motivators. These are obviously invaluable pieces of knowledge in just about any activity that relies on working with others and motivating a team. Considering that the trend in most technologies is that projects are not getting simpler or smaller or "automated" and formulaic, but rather that projects always tend to reach the "edge" of known processes and venture into exploring new challenges and unknown solutions. This tends to make projects bigger and teams bigger and interdisciplinary, with people having to communicate ever more complex and less understood phenomena. And the key to getting people to deal with these sorts of challenges is -- yes -- psychology. Now, it is entirely possible that the profession you choose to apply psychology to may not be all that lucrative monetarily, but that's more a symptom of those jobs being underfunded for one reason or another. But that's not to say that you won't be able to make great use of a background in psychology for very highly-paid careers. And the aim should be to do something you like rather than just something that makes you lots of money. Satisfaction is important. My own education in psychology has never failed to come in handy even on projects that would appear to be entirely technical. People are always the key. And understanding them is important, not to mention comforting.
