#1 Word of mouth... (Good or bad, but good is better, obviously. Well, depends on the person you are talking to.)
#2 Trust... (Better to inform them of all known truths, and let them research themselves.)
#3 Give... (Give them a fraction of a coin at the right time... like now, while it is on the low. Let them see it rise and fall again. However, tell them not to spend it for a year. One year later, I am sure they will buy more, or try.)
#4 Advertise: Buy a Solowheel, and drive it around. (Everyone will ask you about it. Tell them you got it with bitcoins, and use that as the ice-breaker.)
Beyond that, the best you can do to support the network is buy more when they go low, and sell a few when you think they are high. (Not all of them.) You potentially give someone with a long-term outlook, a chance to get one at a price they were willing to pay. Without consuming all the value for yourself. (If you didn't just dump all your coins at once for that high value.)
Make someones day... sell someone a fraction of one, for a loss, if you can afford it. Let them get that gain, which was in your abundance.
Don't panic on lows, or cash-outs... You help the market restore faster if you keep your cool. But don't hesitate to swipe up some of those low values, even if they are not right where you think they will bottom-out.
Oh, and screw with banks... every visit, say to the teller... "Wish you guys accepted bitcoins here"... Usually they say something like, "We might, would you like me to ask"... They think you are talking about a physical coin... Laugh a little and say, "No, it's a digital form of currency, like paypal or credit-cards."
Say the same to any store too.. the person at the register... they will either look to see what it is, or mention it to their boss, if they think you are serious.
Also...
Play dumb... just ask someone.. "Have you heard anything new about bitcoins?" Then mention some news that was good and something that was bad. They will look, possibly, just to feel informed with what you were talking about... like it is something they should have known about. (That is actually how I got hooked.)
Never say crap like..."Dude, your stupid if you don't get some of these!" (That just insults their intelligence, they won't do it just to spite your suggestion of them being stupid.)
"This is going to make you rich!" (They will think you are a sucker for believing that. Then repeating it.)
"This is the best thing ever!" (Trendy feel, pushes most away. They assume you are a noob. Like a kid who just discovered farmville and facebook.)
P.S. Don't preach to the choir... We all are here already, because we believe...
