The reason this works is because our beliefs determine how we predict the future to be if we take a certain type of action in the present. These predictions in turn determine what we do in the present and thus also determine the results that we get in the future.

For example, if you are writing a blog post, you have no way of telling how many people your blog post is going to benefit, but you can believe that it will benefit many – and so put in the effort required into writing. As you write a very detailed quality blog post, chances are that it will actually help more people than a post which you would have written had you believed that the work you do would not benefit other people in any way.

So simply by adopting a belief of a better future we are actually pushing ourselves into doing the actions necessary in the present in order to make that future our reality.
