I have often thought about this concept as both a regular educator and as a dance instructor (now, sadly, a former life). I never saw my profession be any different be it teaching dancing or teaching in a traditional classroom -- helping an individual grow is helping an individual grow regardless of where the help takes place -- but I would often discuss with my colleagues and friends at the time whether we were making a true difference in the world or not. After all, and we would say this regularly, it was not at all as if we were curing cancer or even looking for a cure. We were merely teaching dance, and now I merely teach Language Arts... so what contributions are we really ever making?
I often opted to believe that everything is important but nothing matters. I think in regard to devoting one's life for a cure for cancer that isn't nearly as true, but I am speaking more on a philosophical level. In the grand scheme of things even if we do discover a cure for cancer and our Sun explodes and our Galaxy collides with another and becomes something new altogether, and humanity is reborn with no knowledge of things past, what is a cure for cancer in that grand design?
Do not misunderstand, I am not advocating for a halt to all research and scientific progress or what have you, not in the slightest. I would like to imagine, though, that is some scientist did find a cure for cancer he would not want him to be the one and only to take credit for such a discovery. It would not surprise me if when and if it is discovered it is revealed anonymously for the lack of desire of the assured hype that would follow.
I find it is true in dance and it is true in life: the key to happiness is balance (Luca Baricchi said that once and it resonated with me), and it is paramount to remain humble and remain hungry, to work as hard as you can as if there were someone working twice as hard to take it all away from you. The dancers, and people, who have nothing to prove to anyone will never let even the greatest of accomplishments or victories (over nature, over themselves, over others) go to their heads and detract them from the true intention of existence: helping and lifting up those around them.
When we remember that, when we strive to help and be helpful, even if it is in the smallest acts or words, we have a tremendous power... and while we may not cure cancer, we can change a life in was unknown or unimaginable to us, and then perhaps that person can and will in no small part thanks to us and that small act of kindness.
One can dream, right?
