In a city where a major drawback is overcrowding, and as a person who might just be another average one in the crowd, statistically the city might be better off if you left town. OTOH, if you have above average ambition or ability for improvement and are willing to take that kind of action, the city can become a better place to live just from sticking around and doing more of what you are strongest at in that direction. Especially if you can motivationally leverage that ambition to grow within the crowd. Otherwise you can't tackle the problems where one person is simply not enough. Might be the only way improvements have ever been made in an environment which attracts a crowd to begin with. The micro thing is to not lose the ambition and ability you have now, firm up the foundation as much as needed so you can build stronger actions than could be taken from that point otherwise.
