"It's not about how to achieve your dreams. Its about how to lead your life. If you lead your life the right way, the karma will take care of itself. The dreams will come to you."- Dr Randy Pausch 

What this quote means is that if you choose to live your life the right way then you will always prosper and eventually all good things will come to you. Even if things don't go your way after trying the first time keep trying so that maybe one day you can achieve your goal. Even if you don't make it to achieving your goal the experiences that you had is what makes it all worth it. If you choose to do the right then eventually good things will come your way. Whether its opportunities or a job offer or even wealth or health. All those things will go your way if you choose to live your life right. If you choose your life the wrong way then you wont get anything out of life. Just a lot of pain and suffering. Consequences and all the repercussions of your actions. It is important to live your life the right way instead of just doing wrong.
