Recent research suggests strongly that the odds you’ll succeed improve if you’re intrinsically motivated; that means you want to do something for its own sake, because you feel a deep desire to do it. Extrinsic motivation – wanting to do something for some other, external reason (e.g., better salary, fame, etc.) – can actually impede your success.
What this means is: the odds of succeeding in University increase if you really just want to be here, and not if you’re just here as a stepping stone to a career.
The same can be said about engineering. If you don’t really just want to get an engineering degree, then you’re better off finding a degree you really do want.
