In championship tennis, like in life, a daily effort of improvement and development should not be directed towards the others. In early age of the junior development (and in early years development on the tour), players should not compare each other and value their game based on the results and the opinion of others if they performed better than their opponent. Having this kind of mindset is very closed and if the results do not come early, players could experience destructive emotions and thoughts that would lower their confidence, motivation for practicing and competing, eventually failing to become better and further improve. Of crucial importance is to be focusing on positivity and big picture rather than small negativity caused by current results or other people opinion
