As a fellow individual in the "media" (jounalism/fasion-entertainment) field, I am empowered and continually encouraged by the calibur of show Dr. Phil provides, (and the type of person/people he and his family "portray" themselves to be) and the valuable advice he gives and positive influence he has on many. 
 
Raised in a similar family background and espousing many of the same "tradtions", values, ethics, principals and ideals, I was shocked and disappointed to "discover" in my reasearch admissions that he has failed to live up to and follow the very principles he preaches, especially when he has repeatedly professed that we each (in a relationship) need to think about pleasing our partner 100% percent of the time, that it's "better to be happy rather than right", and that children (and others around us) learn or mimic what they see and NOT necessarily what they hear. 
 
How could you, the good doctor, then turn around and proclaim that you've only seen your (loving) wife's family (sister to be exact) only once in 30 years. You "apparently" claimed that you simply did not prefer driving that distance just to be around kids, but that they are welcome in your home. Well, considering that you too have children (no doubt grown by this point, but I'm sure they too were young during your 30 year union), it may be safe to presume that your statement smells a little "selfish", and honestly you don't strike me as that type of person. 
 
Unless there is something you find staunchly "offensive" and "unaccapetable" about Robin's family (quite like the ethical issues I experience with my husband's family and which I consider blantantly disrespectful and insulting to me and my family), there just doesn't seem to be any good reason for you NOT to want to associate with them or make sacrifices (that just may please your wife), as youj often instruct others to do. 
 
While your advice IS primarily right on the money, I also firmly believe that such self proclimations put you at a "disadvantage" and may result in you losing favor with a segment of your viewers and the population. They will be unable to seperate you professional prowess and experience from the way you have admitted to living and handling your personal life. In fact, they may begin to lose faith, trust, and respect (not for you) but for who and what you claim (to be) and for the excellent advice you have to offer. 
 
Common sense no doubt dictates that we are all human, and fallible and we all have (and will continue) to make mistakes or decisions we are not 100% proud of (even may regret) in our lives, but upon becoming such a recognizable pulbic figure, certain sentiments or statements may prove to be disappointing to many (such as myslef) and perhaps a complete turnoff to others (at least those who choose to unequivically believe what is reported and what they read).  
 
Just my 2 cents worth and wishing you all the best and continued success. You 'do' make many good points despite some "pitfalls" perhaps along the way.
