So, I find that how I view the universe is not the same as others view the universe. Perception is reality, but everyone's perception is different. So for me personally, I felt a flash of lightning and an over sense of joy when I realized I could build things or when I see a technology I don't yet understand. I fixate on it until I can solve the problem. ( my personality type is ISTP) but I am curious, what was the moment that sparked the fire for you? To want to learn how to use CAD or be an engineer?
When I was 5, I liked car and airplanes. My babysitter told me that bears make airplanes :), she didn't want to use the word engineer. I asked my father to buy me a real living bear so that we could build airplanes. He bought me AirFix brand Kits, a Jaguar E type and a Vickers VC10. We built them together. From then on he encouraged me to build and design things, and bought me technical books and tools. Now I'm an aerospace engineer thanks to my babysitter and father.
