There would be a point of time in your life when you learn to do things for the pleasure of doing and not for the acknowledgements. Even if it means that you are not going to get acknowledged for it or worse you are going to be seen as someone not responsible. For you know how much the work means to you. I think it's the point when you know that you have been true to yourself, heck about the others who didn't recognize it. All that matters is the fact that you know the truth.
