Karma will take care of itself.

" Its not about how to achieve your dreams. Its 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 there and on it will be also more easier to try accomplish your dreams will eventually come to you because its not about " oh i have to make my dreams come true ," its about trying so just try and if you think your leading your life in the right direction then go for it.
