There is many times that kids will not do what their parents want them to do as careers. There is also many examples of kids going their own way in life instead of building on what their parents have already built. I think this happens for a variety of reasons, including:
Parents are not transparent about their finances
Parents tend to share defeats and stress far more than they share their successes.
What child wants to go into an industry that they have seen their parents blood, sweat, and tears but rarely see the successes? I cannot say for certain as I am still trying to figure this out with my kids but I believe if you involve them and celebrate family successes that they will see the risk versus reward. Do your kids know what your net worth is? Can they see it change from quarter to quarter or month to month? Have you asked their advice even at 8 years old on what to do or asked them what decision the family should make? Do they see a dad that is always involved in real estate? Do they compete with real estate for dad's attention?
1. Make your finances transparent, who cares if your kids know. Get them involved in the families net worth. Let them see that it is a way to keep score. Celebrate when it goes up and talk about how to do better when it goes down. There is a reason all games keep score and life is just a game, and money is not real.
2. Get them involved in the decision making process. Make a game of getting their advice and pretending to let them make decisions that you have carefully framed for them. What kid would not be thrilled to make a decision on which of three houses to buy, even though the decision is obvious because you framed it that way from the beginning. Being able to tell their friends that daddy buys the houses I tell him to buy is a very powerful and liberating experience for them. Let them be the CDM Chief Decision Maker once in awhile.
3. Get them involved in the hands on and let them see the reward for hard work. My oldest has helped since she was seven to install hard wood floors, paint, etc. I don't teach her that it is a job what I try and teach her is that she is making the world better. By determination and imagination she can take something ugly that no one wants and make it beautiful. You have to frame perspectives for kids. Pulling weeds is not a punishment, pulling weeds is how we help flowers thrive.
4. Celebrate successes in greater amount than you vocalize defeat or stress. No one wants to do something that is boring, stressful, and reward-less. Kids know your business by watching you, and they are soaking up everything that happens, and becoming a veterinarian or a ballerina can be a far better fantasy than fixing up old houses like dad did. However, if they see successes, get to celebrate those successes, and understand that the family is making the world a better place then maybe they wont be turned off by the idea at an early age.
My oldest is now ten and she would rather be with me doing what I do than anything else. I hope that she has fond memories of what we do together and that real estate becomes her passion because it will always connect her to dad instead of being what took dad away from her. I will leave this world similar to how I entered into it...with nothing. So, everything I do is for them to enjoy in their lives, might as well involve them in what I do instead of shrouding it in mystery, and letting them jump to their own conclusions.
Just my 2 cents take if for what its worth.
