“There are going to be setbacks in life.  Even a master or a genius will experience a period of inadequacy when they attempt to learn new skills or explore new domains.  Confidence is what determines whether this will be a source of anguish or an enjoyable challenge.  If you’re miserable every time things are not going your way, if you cannot enjoy it when things are going your way because you undermine it with doubts and insecurity, life will be hell.” ~ Ryan Holiday, Stillness is the Key (Page 73)
