You can be dreaming of the most amazing things, you can have thoughts that would revolutionize the world, but if you don't take a single step to realize them they will live and die with you, and unless in the future we come up with some way to extend your potential beyond your life, they might as well have not been. You as a person are not necessarily important - it's what you DO that counts. But then I think - since your thoughts directly influence your actions (whether you're aware of it or not), and your actions influence others' actions, and likewise others' thoughts, then there is a real impact your dreams have on the world, even if they are not directly expressed. So maybe things like how you see yourself really DO matter, because they would limit & extend the range of actions you're willing to take, and therefore what kind of ripples you make. What do you think?
