Talking about motivation is a non sense, how could we motivate people different from us with their own views, thoughts and values?
What we can do is to inspire people, if we want to treat them as empowered individuals.
The possible approach: instead of motivating, try to inspire others: this means that we need to talk to them, tell them stories in which they can find inspiration. Talking about our dreams, our experiences, our successes, our failures and our feelings is what we need to increase the inner motivation of others.
Stop motivating and start inspiring people!
