Before you even started that application, your first choice may have been deciding to go back to school, perhaps to aid you in making that career switch, or to improve your chances for a promotion at work. Whatever your reason, part of the process involved looking at schools and choosing which of those you wanted to actually apply to and whether or not their requirements really involved taking that dreaded GMAT. Somewhere along the line, you contemplated what you wanted to write about in your application essays. I found that process to be very reflective - even if you aren't thinking about going back to school, it's still a good idea to think about how you've changed over the last five to ten years and what your goals are over the next decade.
Once you've been accepted by Haas, the choices that are available seem limitless. Which cohort do I want to join? Evening or weekend? Do I want to take the bus or can I find someone to carpool with to school? Which clubs should I join? In the second and third years, what electives should I take? How many bid points do I use? Should I go to the football game or read my case study (and yes, you can do both and sometimes you can do both at the same time depending on how the game is going :p).
As with any worthwhile endeavor, surely, sacrifices will need to be made. You'll need to know your priorities well before you begin school. Do you need to spend some much needed time with your family? Or do you need to be at school at the discussion session? Some of these choices will be challenging such as - Which of these companies really is the right place for me? And others will be clear - yes, I want to go to sleep, but I need to finish this last case study writeup.
If you've made the choice to apply to Haas, I wish you the best of luck and hope to see you here on campus soon. Cheers!
