I really like working with my hands, I like to get down and dirty but I also love math and science especially when applied to aerospace. For example there was an article where NASA had started using 3d metal printing to produce complex parts with honeycomb structures reducing weight but not sacrificing performance. Would an aerospace engineer get to design a part, for example the fuel injector plate of a rocket engine. Then hit the print button and hold the designed piece in his hand a few hours or days later. Then take that piece to the lab and test it and see how well it works and document his findings. For example take a look at these pictures, this is the stuff that I want to be doing and I just want to make sure that I am not going the wrong way. I know it may be a bit childish to include pictures but I really dont want to just sit in a cubicle doing math unless there is some real product that I create or test later on.
