Raise or Lower Expectations

Late last year, I finally received an IB summer analyst offer at a BB. This was an extremely exciting milestone for me as I come from a low income family with parents who have worked long hours their entire life to give me every opportunity they could. My life goal is to return the favor by taking care of them financially and helping them travel the world to see the things they were never able to see.

But do I raise or lower my expectations? Is this goal feasible for someone taking an Investment Banking path? If it is, how many years before I can comfortably support myself as well as them?

I can't be the only person in this exact same position and am curious to hear insights from people who have spent some time in the industry.
