big

Most people are much bigger than their everyday life allows them to be. Playing with a toy train set can assuage this- you become Gulliver for a while. Or amateur acting. Or talking with a really loud voice. Or being alone in the wilderness. Or running your own company. There are probably quite a few other ways that stop short of megalomania too. Less useful is latching on to someone, or thing, who is already big and becoming a supporter, a number one fan, a coat-tail rider...reflected glory has none of the nutrition of earned glory.
