I need the conclusions: what is the characters motivation for decision, or change. I need one for each lennie and George

Lennie's motivation to change (behave himself and stay out of trouble) is to allow them to make enough money to buy the farm.

george has the same motivation, although it has nothing to do with behaving himself. He'd like to have the farm as much as Lennie, but he'd also like the independence that comes with working for himself.
