Investment Banking

I've accepted my offer to Commerce. I know that the main strong points for Commerce at Queen's is Finance (I think), Consulting, and Investment Banking. I was looking into IB and it seems like a very successful career with a lot of money. However, you're working 60-80 hours a week, which is insane. There is no balance between social life and work life. I wanted to know if this is worth it and if not what other careers are there that I can get from this program that generates good money and that gives me a good balance between social life and work life.
