I think this song is about having all these different paths in life, a whole bunch of options that you can take as careers or whatever and trapping yourself into something that ultimately won't make you happy. And the decision to do what you want, even if it isn't a good idea (such as aspiring to become a musician when it's rare that you'll make it anywhere) and freeing yourself from the confines that would make you a prisoner in your own life. Making the decision to take a risk and jump into the unknown, and being free to follow what you want to.
