I think it's better to just concentrate on a network of people with you can share values/thoughts or even just sympathy rather than try and spread to everyone as you say, it's just a waste of energy, it's like try to excel in every possible study field

The familiarity is a good example, I have built a "network" with local shops, they know me, make discounts or accept a later payment and stuff like that, all this came over much time when you built the relationship but you can't get familiar with every store in the city
