Is it a bad thing to switch your major?

I switched my major three times in college and I am glad I did. Well, I wish I hadn't done it three times, but the fact of the matter is that an area may sound interesting to you at a high level, but once you get into the details you find it isn't what you expected. I would absolutely change majors in such a case. For me, I was lucky to realize early (sophomore year) that I wanted to change AND the changes were not huge. I was changing from math to physics to engineering in my case. Which means that most of the basic courses I had already taken would still count against my new major. If you are considering a bigger change (like from math to poetry) and you have been a math major for a few years, it becomes harder to switch and not impact your graduation date and wallet since you need to meet the requirements of your new major. You do need to take those things into account when deciding whether to switch or not. But if you really feel you are in the wrong major and feel you now have a much better idea of what would be the right major, I would try to make the change.
