Qualities you need to get through medical school and residency: Discipline. Patience. Perseverance. A willingness to forgo sleep. A penchant for sadomasochism. Ability to weather crises of faith and self-confidence. Accept exhaustion as fact of life. Addiction to caffeine a definite plus. Unfailing optimism that the end is in sight.
