Over confidence is unnecessary.
During the doubles tennis game featuring BrookeDoane/AnnaYang, Doane kept making unforced errors with her volley.
She was underestimating her opponent, thus affecting her level of focus.
This can lead the opponent to gain confidence and cause an upset.
You always want to put the pressure right from the beginning until the end of the game.
It’s like studying right from the beginning of the semester and not letting it pile up.
We can all learn that too much self confidence is dangerous.
Confidence should have its limit.
