It must be !!

Quitting is not giving up,
It's choosing to focus your attention on something more important.  
Quitting is not losing confidence,
 It's realizing that there are more valuable ways you can spend your time.
 Quitting is not making excuses,
 It's learning to be more productive, efficient and effective instead.  
Quitting is letting go of things (or people) that are sucking the life out of you
 So you can do more things that will bring you strength.
