Advice for people wanting change in the world

I figure I should say this briefly since I do have a little bit of free time right now. I've grown a bit tired of people complaining about how things need to change, yet they are doing nothing to make it happen. Regardless of if it's interpersonal relationships, to large political matters, this is a concept that can apply to all levels. If somebody wants change, yet won't reflect that change themselves then that is rather hypocritical and damages their message regardless of if they are right or wrong. I hate to have to point out this basic reality, but given what I've seen in my private life this past month I felt rather compelled to make this statement.
