Start with why! I’m fairly religious so is my brother. We are both MDs, 21 and 38 yrs in the service of man in different areas of Primary Care. Work is 60-80 hours per week, half of which is non reimbursed. We are both happy. My oldest D is on the same path now and has that same commitment. Profession first, doubtful on motherhood. You need to have that higher purpose to see the light through the tunnel. My younger D does not have that make up and is choosing a different path. Prestige, Power and Money will NOT be enough!
