I am 41 and it's certainly more difficult at this age because people my age are busy with family and work. Friendships ebb and flow based on external factors. Having realistic expectations is important.

I work for myself and generally with my work I am not interacting with people on a daily basis. I also got divorced two years ago and since then, I've made a concerted effort to be more social and do a better job keeping up with friends. I've made quite a few new friends since then, and several that I see at least a few times a month.

My take-away from this article mainly was that making yourself vulnerable makes someone else willing to share too. It's valuable to get to know someone better. I don't think it has to be done in a scripted fashion. For me, the opportunities tend to present themselves organically.

I've had some deep conversations taking a ski lift up a mountain, walking around on the street knocking on doors during a campaign, waiting around to launch at a flying site and on a long drive in a car. You'll probably learn that you have a few shared interests with that person. When you do, it makes finding opportunities to get together and do stuff easy.
