Being able to persuade some people is a lot harder than what it may seem. A bandwagon is one way, and what this means is that you persuade them to do it by telling them that everyone else is doing . The most effective way for me personally is reverse psychology, because when some one tells me that I can't or won't do something, the first thing I do is prove them wrong. There are many different ways to persuade people and if you are good at it, you can convince somebody to do almost anything.
