This song is about choices. About how your present circumstances usually are the culmination of the choices you make good or bad. You are bound by the choices you make. If you buy a car you can't afford and it prevents you from paying your other bills than you are trapped in a financial prison you created. That is a simplistic example but one nonetheless. It could be drug addiction alcoholism or whatever. The cool part is how in the song he talks about accepting his choices as his and being accountable for them not making excuses and accepting the repercussions.
