Timbo's hopeless slice

Hi Timbo. I was wondering why your signature says "Tennis isn't easy." Corners. Do you mean that the objective of tennis is to go for corners and the game is essentially simple? Sounds simple but its only those who have the necessary tools to make it simple that can go for corners. Essentially thats what pro tennis is IMO. Is this what you are referring to? Also, what ive noticed in pro tennis is. The player who goes after the corners better usually wins the set. Would like to here your opinion.
