What are your table tennis goals?
And before you say them, remember this. There are two voices that will constantly ridicule your goals if they are too high. One is from some other players, who may not have the same lofty goals for you that you may have for yourself. Ignore them, and go for your goals. (Though it is helpful to have reasonable goals - just don't limit yourself.) The other is that little voice inside your head that says, "You can't!" Ignore that voice. In the words of Albert Einstein, "Great spirits have always encountered violent opposition from mediocre minds." So drop the mediocre voice from your mind and let the great spirit soar.
Illegal hidden serves one more time (until next time)
<Begin Rant>
Dear umpires, coaches, and players, let's go over this one more time.
Rule 2.6.6: "It is the responsibility of the player to serve so that the umpire or the assistant umpire can be satisfied that he or she complies with the requirements of the Laws."
Read that over once or ten times, and it'll still say the same thing. If you aren't sure if the server is hiding contact with his serve, then you aren't sure he isn't, and the server is not serving "...so that the umpire or the assistant umpire can be satisfied that he or she complies with the requirements of the Laws." You can give a warning the first time, but thereafter you must call a fault. If you do not, you are not umpiring; you are allowing one player to cheat, and making sure more players will do so since they see umpires are not enforcing the rules. You know, the rules, the ones umpires are supposed to enforce?
