I agree. I think the only thing we can do is do our best to dictate our actions in a way that creates possibilities in the universe that our dream will come true. The more actions we do and the more possiblities we create, the more likely our dreams will come true :)
For example, right now, I would like to advertise my company. Each time I write a post online about my website, I would argue thousands of possiblities "spawn". Each providing me a little chance to get a client, and move closer to my goal. It's all we can do to create these possibilties for ourselves, and hope fate has our side. :)
