Same problem for me.

Anyway, call me mad, but we are too used to believe that each specific domain of knowledge must take years to be fully understood. That is just not true. What is stopping you from going from engineering to economics, or from business to programming, or from medicine to architecture, etc.?

The real shame is that we don't have a proper learning system. Universities are wasting the time and brilliance of millions... the real learning is on the field or sharing with people or reading (alone) good material. And that doesn't take too long...
