That's a horrible one. Minor details are the bricks of a relationship, the closer you are the more bricks--in quantity or quality--you contribute. If you don't have any bricks to offer, it is difficult to establish or to sustain a relationship. For instance, small after work gatherings often seem a waste of time, especially to those who aren't innately fond of socializing or unable to proficiently judge the value of such, yet exactly these have a chance to provide a more intimate atmosphere. Also, even a single wasteful meet-up might count as a step and with some number of steps you'd also cover a bit of distance.
As such, it isn't that there aren't meaningless meetings but it's the recommendation to evaluate and avoid such that is misleading.
Instead, one should be aware that because one has to invest energy to socialize one automatically tends to avoid doing so at all, which again reduces the amount one can store. Hence, do not avoid spending your energy supply but learn to judge the highest and to improve your returns on investment. What good return supposed to be is subjective but one shouldn't forget that profound happiness and success is build not suddenly acquired.
>7. Have more meaningful conversations and less small talk. Research suggests that the happiest people have twice as many meaningful conversations—and do less surface-level chitchat—than the unhappiest.
Avoiding small talk won't lead you to more meaningful discussions. It's common sense that people are happier if they found someone to converse with more in-depth but that doesn't reduce the value of small talk. You can't reach the station of happiness by skipping the traveling part, and traveling is often like long grinding work.
By the way, inversion isn't about the ability to socialize. The lack thereof is just a consequence of a more isolated course of life.
