Be interesting, do cool things and invite someone in to join you. Thats damn solid advice.
People often think their hobbies are boring or to niche and think that no one will care about them. But passion is infectious and by sharing things you think are interesting you will eventually find someone who wants to share it with you.
And we can predict what will happen pretty well and adapt to the situation dynamically. Our only weakness is that we do stupid shit like drunk driving, speeding and not paying attention.
