Even though I do believe you have to be a practitioner and that you actions every day are the main part of what happens in your life, it all starts and end with the mind. If you don't believe, your chances are 0. If you do believe, you have all the chances, and opportunities the world has to offer. From personal experience I can say that if you have the right mindset together with the action to prove that you do, life or the universe or whatever you may call it, will always meet you half way :)
