Easy rule of thumb: the more interested you are in others, the more interesting they will find you.

To be interesting, be interested.

Not in a phony way, and certainly not in a manipulative way.

But one of the rules of my life is that virtually everyone you meet is an expert on *something*. It could be anything from early jazz to early Studebakers to model airplanes. But in some field somewhere, that person has an expertise you can learn from.

Find their expertise. Be interested And grow.
