When times are tough (as this author is unfortunately going through) your support networks are crucial. Family, friends, and (if you have it) your faith in god. This is earned however - if you have lived a miserly, unhappy life then don’t be surprised that few show up when you are in need. You need to show reciprocity and be a good brother, friend, and community member when times are good as well.
I don’t discount how hyper important the individual is - it’s extremely hard and isolating to raise your hand in class, publish a contrarian idea, start a business, ask someone on a date, be a stand up comedian, write and perform music, and all manner of things that you yourself must get the courage to do. And these actions are what move society forwards most.
There doesn’t have to be a dividing wall between the individual and the community. You grow your support network by watering it like a garden, weeding out the bad plants, protecting it from poor weather. You have that as your base upon which to build towering castles.
