I can honestly say this is not a phrase I even use. For me this would embark all kind of feelings, fear, laziness, closed mindedness and a big stunt in my growth. I am always a work in progress. It takes some self motivation to be able to conquer such a feeling. I think we all have moments where it is hard to motivate ourselves but if you train your inner voice to be loud, strong and honest,you won't sit back and be set in your ways. On the other hand, if you are set in your ways and are happy with where and who you are, then who is anyone to tell you different? In the end to each his own. For me, my work will never be done.
