Instead of trying to fit the mold of a "perfect applicant", focus on trying to figure out what you enjoy doing and do it. Although, if you're dream is H/S/W, working in consulting/i-banking/or starting the next Facebook doesn't hurt.
Not sure I quite agree with the consulting/IB comment. You would end up competing against other consultants/IBs and if that's not your passion you're not going to be able to stand out amongst the others.
I do agree with doing what you really enjoy though. Business schools look for a consistent story and as long as you do well in what you enjoy, you should be in good shape. If your community/extracurricular experience also lines up to that consistent story, even better.
Also - if I knew what business schools were looking for all along, I probably would have done a better job documenting my career successes as they happened. Thinking back 3 years to an exceptional leadership experience can be tough. The details fade. If you keep your material well organized, you should have some really good examples to begin writing your essays. Similarly, either write your GMAT soon (if you think you'll be applying within 5 years) or keep your skills sharp over the years. Pretty sure I could have picked up another 20-30 points if I was still in "school mode."
