Host a really nice dinner party every week. Start with a group of legit people you know. Do it at your home if it is big enough, or at a nice restaurant. Pay for the whole thing. Ask each guest that the only thing they need to do to pay you back is to introduce one new person to a future dinner party. If you've done your job right, they'd be overjoyed to refer someone (free dinner + awesome people = huge win)
Let's say you have 6 people at the dinner party. $60 per head = $360 per night, which is $37,440 over the course of two years, at which point you've made 520 really great connections.
What ways are you referring to?
