"It's not about how to achieve your dreams. It's about how to lead your life. If you lead your life the RIGHT WAY, the Karma (destiny, fortune, good luck) will take care of itself. The dreams will come to you."
    ~Dr. Randy Pausch

I think what this quote is saying is that if you lead your life in the right direction then from it and on it will be also more easier to try accomplish your dreams will eventually come to you because it's not about "oh, I have to make my dream come true." it's about trying so just try and and if you think you are leading your life in the right direction, then go for it.
