A benefit of so many people in one space is the opportunity to find your like-minded tribe. People who understand your world view, who enjoy the same things as you, who help each other to feel like they belong. Life is far richer with beautiful friends. There are lots to be found out there so be open and engage with everyone you meet. Simply being polite and super-friendly will open doors and reward you with smiles from people who understand. With this attitude, even a quick visit to the local shops (do shop local) will be a happy and nourishing experience.
There are groups and gatherings for everyone amongst the diverse communities of the city. Go and be a part of your unique clan. Meetup is useful here. As are the notice boards found in alternative shops and cafes.
