Collage shortcuts

I just have achieved my 2000th collage and put on my web site. Frankly, I am really surprised by this number, counting the last 50 in "years". Now I am in 2001 already, getting closer and closer to 2009. How many will I be able to make in the future. Can I maintain the quality I am after? When I was young I dreamt of one single masterpiece, bringing me glory and wealth. And there I am, with my A4 sheets, which are fragile, to be handled with care, away from direct sunlight (I refuse to varnish them - they would become a painting). But I love them all. And if I can, I'll go for another thousand.
