Small hack to find your people.
Instead of saying "I have this idea to do XYZ ..." say "Has anyone thought of doing XYZ and how could I join/help?". The thought here is that everything you can think of has already been thought by someone else. And instead of letting your ego win by hoping you, and only you, are the best leader for this idea, understand the power of ideas that are free to roam and find new friends.
