Have you heard about "The Secret"?

It was popular a few years ago about visualizing the things you wanted in the future and lots of people would spend their time imagining themselves driving a fast car, living in a dream house etc. The problem is, the imagination is so powerful that once you imagine it well enough, your mind and body thinks it has already been achieved.

I feel a lot of our life is like that now. We sit down in front of a driving game or FPS and think we can race or go into battle. We watch a surf movie and feel like surfers, we read tweets and think we know about the world and we google answers an think we understand in practice.

There is no need to actually be something, just make it look like you are that thing, and the imagination will do the rest.
