I completely agree with this one. Lots of people think being a liberal arts major is easier than a science degree, but there is so much subjectivity going on in the grading systems that it can be hard to get an A in every class. I speak as a history major, and it could be hard sometimes to figure out what a certain TA/prof wanted or why I got a B on my last paper. Sometimes I would even long for the bio tests where you could get a good grade just through studying and knowing hard facts. Now if you wanted to do no work and were OK with getting a B in every class, liberal arts is the way to go.
In the end, just do what you like. There is no reason to waste your college years on something you don't enjoy just to "look better" to adcoms, or whatever.
