Pain is nothing compared to what it feels like to quit. - Unknown

Depends. Sometimes we have to change directions. Is that quitting? I don't think so. Doing what is right for our own health and well-being is more important than pursuing what we once thought we wanted to do. So, in that sense, quitting is good. When something is no longer moving us forward in a positive direction, it is time to reassess and take appropriate action, whatever that is for us.
