Everyone wishes to leave a mark on this world. What kind of mark is up to them. But sometimes our unexpected actions lead us to make some of the greatest marks in our history. Someone once said "the best way to predict your future is to create it". Don't sit around wishing for things to happen for yourself, go out and find ways to make it happen. As an artist I suppose I can use many mediums and tools to create my future, but i'd never use an eraser (not even a kneeded [sp?] one). For your past leads you to the present and you can always change your path from there.
