Being Part of a Collection

For many years now it has been a secret dream of mine to be part of a photography collection (private or museum). I guess it's a selfish dream but I always thought it was important to have your work collected, so that after you die you leave something behind. There just seems something meaningful to be gone physically but to still have a piece of your heart, an important piece of who you were up on a wall some where interacting with strangers. It is a selfish dream but no ones perfect : )
