Basically, what do you think the point to life is?
Odds are you will contribute little to nothing to the world, and will just be a breeder who hopefully doesnt screw up their offspring too much.
Depending on life expectancy after your grandkids or great grandkids you wont be remembered for anything or by anyone. At best you will be an old photo or video and maybe they will remember your name.
Sorry if thats depressing, but does anyone have a better answer? Im guessing not, otherwise youd have a book on the best sellers list.
How many here are just going through the motions of what you are "supposed" to do? ie. goto school, get a job, find a mate, get a house, work for many years, retire, die.
