Dont specifically look for people who might be extraordinarily talented because those people will typically be working for a huge company getting ridiculous amounts of money but have no say when it comes to what the company does, or they work privately in consulting. The people who are good contacts are just normal people, they can let you know if their company is looking for people to hire or one of their parents might own or be on the board of a company who is looking for people. There are many situations where just being friends with people can help you out, so don't think of it as finding contacts but think of it as just meeting people with the same goals as yourself.
