I find motivational videos to be corny, they don't do anything for me. Understanding myself and how and why I behave the way I do works for me. Some level of routine (which I've trouble with) and semi-discipline. Whether or not there's different types of motivation is hard to say.
I don't think I really motivate anyone. Not through any conscious effort anyway, though some people may be motivated to do xyz based on their incidental interactions with me. I generally leave people to do there any own thang and have to no motivation to motivate, har har, and I think I lack the charisma to do so as well.
Different things motivate different people. As far as how that differs from the past, that's too broad a question for me to answer. Lotta factors there.
That said, there's things that fire me up. Metal in particular.
