Hey, don't say that! Someone else could've been an Olympian, or a Noble Prize Winner, or a Movie Star, but you were the sperm who made it! You won the race and you were eventually born, you are one of a kind and you can't be replaced. You will accomplish great things one day, in fact you won a race before you were born! That should be an achievement on its own!
also..big deal part of your dna wabbled all the way through your moms vagina in form of sperm cells. thats not a very "optimistic" thought now, is it. face it if you arent a big achiever none of the other sperm cells would have been either
Also, why do people still think that we come from sperm???
