If you have not read, The Last Lecture, by Randy Pausch then you are missing out! This man's life was taken far too early, as many peoples are; but the insights he gained, as he 'lived like he was dying' are life changing for all. No matter the wall, if you want it bad enough, you can get through it! BELIEVE!
"Brick walls are there for a reason. The brick walls are not there to keep us out. The brick walls are there to show how badly we want something. Because the brick walls are there to stop the people who don’t want something badly enough. They are there to keep out the other people."
"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 will take care of itself, the dreams will come to you."
“You have to find something that you love enough to be able to take risks, jump over the hurdles and break through the brick walls that are always going to be placed in front of you. If you don't have that kind of feeling for what it is you are doing, you'll stop at the first giant hurdle.”
