I like it too. If you want to be a runner, act like a runner. To me this means, dress like a runner, eat like a runner, and get out of bed and run every day like a runner. When your are educated about what it takes to do something and you match those behaviors, you will be well on your way to being exactly that... And when you are actually doing those behaviors, there isn't any more pretending.

But that's actually a bad idea in many cases. If a severely out of shape person decides to act like a runner by running everyday, he is very likely to hurt himself relatively quickly or need physical therapy, especially if he is overweight.
