1. Stay humble. You're just a doctor. Outside of the hospital, you stand in line just like everyone else does. You still need a colonoscopy at 50 just like everyone else. Your wife /husband is still not impressed--you've still got to change the diapers, wash the dishes, and take out the trash.
2. Your learning is only beginning and will never stop (true in life, but esp. true in this job).
3. Learn to try your best and accept the results, even if your best turns out not to be the best.
