I'm not sure. I definitely did not become a doctor to make money. The time and energy I've put into the doctoring gig would have been more richly rewarded in other pursuits. I don't worship money or what it buys. I give a lot away.
I've taught my kids that it's impossible to have a meaningful life without serving others. My son is thinking about a career in medicine and I'm encouraging my daughter to consider law school. There are countless opportunities to serve in nearly every profession. My son does work for Habitat for Humanity and my daughter volunteers for a local wild animal hospital. My wife volunteers at a local crisis nursery for abused/abandoned children. A career in law does not mean you are greedy or self-serving. (that would be Real Estate sales
)
As a parent I encourage my kids to achieve a professional vocation for a lot of reasons; independence, flexibility, security and of course the opportunity to serve.
