Any restrictions you think that you have in life are all part of your imagination. The sky is truly the limit: if fact, if you want to take that to a literal extent, go skydiving if you wish! The only thing that holds you back is your very own conscious. Go beyond your fear and do what you please. If you aren't doing what you want to do with your life, then you AREN'T FULLY LIVING. Imagine the possibilities. Then go out and do them.
"The whole point in being alive is to evolve into the complete person you were intended to be." -Oprah Winfrey
