Agree with the above statements. Being spoiled does not hinder a career, however irksome it is for you.

You were taking comfort in heaping contempt for your roommate as a defense mechanism against your envy, which means that when your beliefs were disproved, you lost your balance.

Life is unfair, suck it up. Somewhere in the world some kid is digesting himself to death because of hunger, and another person just crashed and will remain paralytic for the rest of his days. You are sound of limb and body, but still dissatisfied... how unfair is that? Life does not own you anything, and does not have a reclamation's office. On the other hand, use your envy and jealousy to power yourself, and learn your lessons. This guy just showed you that you need to try to succeed, so be grateful for the tip and make sure to try yourself when you have the opportunity.
