I did NOT say you should try to appeal everything you feel is unjust. I said let the person decide. I'm saying there should not be a blanket statement about NEVER appealing certain decisions. People should appeal for anything they WANT to (obviously after using common sense, not everything) especially if it's NOT personal, like college admissions.
I also did NOT say you should appeal to 1,000 different places. It was an example to point out that Paul was comparing apples to oranges.
And, by appeal, I don't think either I or Paul meant just words, but whatever it would be (retaking the physical, sending videos to a coach of your performance, sending a college a picture of a national award you just received in March after you were just rejected, etc.)
If your partner breaks up with you, for example, appealing to 1000 different committees is only going to make things 1000 times worse for you.
You've got to decide whether the reward is worth the effort. Sometimes the reward doesn't make sense if you had to fight to get it. (eg, if you're not picked for a team then bitch your way in, there might be resentment that brings the whole team down such that you'd have been better off not bothering)
