I don't know, you guys. I understand what you say, and in my 1,5 year here I've seen what you describe, people who will complain no matter what. But my view is that, forget 10 and 15%, if even ONE person understands the information and changes accordingly, becoming more educated on processes and stuff, then it's a gain and it's worth doing. Again and again, patiently. That person will gain something, we will gain something - because she will probably start informing others in turn.
Maybe it comes from my calling as a teacher. I have helped many people that other dance teachers insisted were hopeless or not worth spending time and energy for. They didn't become Nagwa Fouad or Soheir Zaki, but they improved spectacularly from their departure point and for every little improvement I had this exhilarating feeling of accomplishment.
That's why I'll never be tired of trying to communicate and give information. To those, few or not, who are willing to receive it and propagate it. After all, most of the time we can copy-paste a little message we have saved on our hard drive, so it takes literally seconds.
It has happened - many times - that the person we reply to still not gets it. Others have written "Oh, that's how it is? I didn't know, thanks for explaining".
Whatever the response, we must keep in mind that for the one person who replies to your post, there may be hundreds who also read it, those who are not into writing much. You never know its impact, whether it has reached only the person you are replying to or many more who had this question in their minds and now it has been answered.
It's perfectly ok if some of you are sick and tired of doing it. But I think it's also ok if some of us still insist on trying.
