Grades, MCAT scores and great ECs (including compassion for the poor and undeserved). Also studying abroad and being fluent in more then one language helpful ( Spanish and French are the most helpful). Get associated with organisation like Americorps. Get CNA and work AND volunteer in medical environments and homeless shelters. Also make sure you have enough time for yourself and have some fun.
When it comes time to apply to medical school, if you have scores for Hopkins and you are still interested apply but whatever you do don't apply just to one school. If you have scores for other top tiers add them to the list. If you fail to get into Hopkins, you could get into Wash U, Columbia and other great schools. Then you have a second chance to go to Hopkins by scoreing a Hopkin residency, which is where your best learning experences will be any ways.
Stay guning for the highest, don't run over anybody on your way up and pull some of those less fortunate then you up with you and you will be just fine.
Second point, don't joke about suicide please. It is never funny.
