I am now a Control Systems Engineer - I conceive, engineer, design, install, and startup digital control systems for large industrial process to run the process in a safe and efficient manner. My degrees are BSEE and MBA. I just "knew" that I wanted to be an engineer since junior high school.

As a note: in all States in the United States (I believe) one is required to be license by the State to use the title "Engineer". Some States allow individuals who run trains also be titled "Engineer". This means that is not legal to have business cards printed that say "Control Systems Engineer" unless you have a P.E. I understand Europe has something similar. If you have an Engineering degree, you can call yourself a "Degreed Engineer". In theory, you are not allowed to practice engineering if it will affect public safety unless you are 1.) a P.E. or 2.)are working under the direction of a P.E. The most States do not enforce these laws, however. To some extent is like the licensing of lawyers - you cannot practice law without passing the Bar Exam - which you can't take without going to law school. It’s just that lawyers like going to court more, so they enforce the law against unlicensed lawyers more. Yes, I am a P.E. and it a sore point with me.
Having said all that, if you have an interest in making things work and dealing with trade-offs, then engineering is the way to go. If you want to understand how things work and make new discoverys, become a scientist.
