@Tifinden,
We should worry, I believe, for as I do not want to end up living like a hobo on the streets, I study for tomorrows test, I prepare for my upcoming piano lessons, I am ready for my job interview tomorrow, do you catch my drift? This is why I prepare for the upcoming day. It is exciting, therefor our minds can't hold back what could happen. Thats why some kids dream of becoming rockstars, and become them! Or some kids grow up to be astronauts, or even might be the president! It is so exciting to think about thing, like how you could think about getting bitten by a radioactive spider and becoming a superhero! I rest my case for now, and I will comment more later if i have time.
