Why does every woman want me (the doctor) to tell her husband to do things she wants him to do eg. exercise, not drink, come home on time" and @sarikaphatak replied: "@netshrink that's called 'Sonarane kaan tochane' 🙂 you have much more cred than the so called 'nagging'. effectiveness needs to be studied"
I have also been in a similar situation (i.e. situation similar to @netshrink's) often, except that instead of woman and husband, in my case it is typically mom and child. It's either a school kid who's probably not studying as much as the mom wants him to, or a college student who is partying too much, or in some cases son/daughter of marriageable age who is rejecting the parents' matrimonial suggestions.
The mom ends up telling me: "He will listen if you tell him."
You know what? Most probably, I'm not going to tell him.
The reason your kid listens to me is because I don't nag him about every damn, trivial thing that you feel compelled to improve in your kid.
The reason your kid listens to me is because of the 100 things that I feel like telling him, I only tell him 3, and keep the remaining 97 to myself. Because, frankly, (and this is true of everything in life), of the 100 things that you worry about, only 3 are really worth worrying about.
No, I am not going to tell your kid to read "educational" books instead of the "trash" he reads. I think the "trash" he reads is fine. No, I'm not going to tell your kid to not play the obscene 'Grand Theft Auto: Vice City.' There's nothing we can really do about it, and might as well focus on ensuring that he grows up with the correct values, inspite of playing GTA: Vice City. No, I'm not going to convince your daughter that she should agree to marry that nice Software Engineer in New York, who makes a lot of money, but is not interested in movies, or books, or sports, or travel. The reason your daughter listens to me is because I don't give her stupid advice like this.
Indian mythology has this interesting concept. Sadhus and rishis acquired great powers through penance, but their powers reduced every time the were used. Hence they had to be a little careful before using their powers and randomly cursing people. That, I find is a very useful piece of insight – your power increases when you don't use it, and decreases when you use it.

Now, if I could only follow the above advice when parenting my own kids…. but damnit, it's too difficult to do on a 24×7 basis!
