Success Trains, Failure Complains
Rosa Coelho | March 23, 2013
Are you a complainer? We’re not just talking about working out and nutrition we’re talking about everything.  If you are a complainer catch yourself next time and STOP.  Complaining gets you no where. If anything it sets you back. It becomes a downward negative spiral.
