Anyone who exercises regularly can tell you how true this “If It Doesn’t Challenge You, It Doesn’t Change You” quote is. Those folks know that they must go a little faster, add a little more resistance, get that extra rep and push themselves a little further to gain muscle, lose fat and increase their level of conditioning.
Conversely, they realize that if their workouts occur in their comfort zone then they will not physically progress and grow. The same is true intellectually with your own personal professional development.
In order to break through to new levels of success you must challenge yourself to be better every day. Read a great book, make that extra sales call, give extra personal care and attention to customers, commit to continuous improvement and being a true student of your profession and you will change – for the better!
Make a Great Day!
