Well, that would make a long list. 1. I always had a thing for commerce ( as a result it was my subject till 12th). I found it more realistic and relatable ( though I don't chase money blindly) 2. Professional courses like C.A., and C.S never gathered my interest simply because they could easily tie you up to one field, narrowing your vision to a unilateral one. ( I appreciate their professionalism though) 3. I always wanted to be part of policy formation at the apex levels. Commerce ( and it's bachelors degree) can take me there faster than anything else. 4. I love the subject and I think is valid enough to be the only reason too.
