It is the fake it till you make it theory. It is not a matter of pretending for the sake of pending but more a matter of creating an image of ourselves that can convince us that we are really more than we might think.

Well said.

@Evelyn: I guess it depends on what you are trying to achieve. If it is a change in behaviour then pretending or rather fully acting in the desired way works well. Their will be internal resistence (like fear) which has to be dealt with.

On the other hand if you want to be someone who can work anywhere in the world changing countries every few months then you have to take it step by step in order to ensure you have the physical required resources to sustain such a behaviour.
