So, I was an ME major. I was doing fine, maintaining a 3.8 GPA and really loving some classes. Then I got a job doing video work, which I have always done as a hobby and, long story short, I switched majors to digital media and broadcasting. My average graduating salary dropped by something like fifty grand and on the surface it probably looks like I did the wrong thing. I did keep ME as a minor so that all my credits were not wasted. I think that your situation is different though. You don't love it and your not sure about it, but everyone has those moments about any major and college in general, it's part of growing up. Unless you believe you have found your calling and it is not engineering it is not worth it to quit. We are all lost at some point in college, that's part of the game, part of the challenge. You have invested two years of your life in engineering, is it worth it walk away now? Don't leave the path you are on just to wander, if you find your right path then by all means ditch engineering and hop on it, until then invest yourself fully in the path you are in. Also, if you do change majors consider keeping engineering as a minor, I know for me I have only eleven credits left to get my minor after I switched halfway through my sophomore year.
TL;DR
Don't leave your major to wander, leave it if you find your calling. If you do change majors consider getting a minor in engineering.
