"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." by Dr. Randy Pausch

I think this quote means that if you make good choices in your life, there is no need to worry about getting to your goals. Also that if you lead your life well, all the good luck and fortune will come to you. If people try to bring you down and you keep on making right choices, the carma will hit them back. So you won't have to worry about those kind of people. Choosing the right can get you to where your goals are. But if you make wrong decisions in your life, you might not get at all close to your goals. Being friendly to others is a big part of achieving your goals. This is because if you need someones help, you want to ask someone for that kind of help. So by living your life well and making the correct and feel-better decisions will get you to your goals. But it is all you, you are the one who can decide if you want your goals to come to you.
