No problem, the best thing about anything is to be educated about it. If you don't like engineering, don't do it. If you don't even enjoy it in the slightest, you will fail miserably because you will have no desire to work hard. Engineering isn't even that difficult, you just have to work hard. But like I said, if you switch yourself majors and you find yourself cruising through it, pick up a minor or double major in something.
Also, people say do whatever you want which i agree with slightly. Do whatever is going to make you happy, but get enough credentials is school so you have an unlimited number of options when you graduate so you can really do whatever is going to make you happy.
