Another lesson in never giving up

Hello all. Well, I learned something recently that reinforces my previous posting regarding never giving up.
Ok, you know WD-40...well, it's one of my favourite products. I use it regularly on my bicycle chain and also sometimes on squeaky hinges, you know, the usual.
Well, do you know what WD-40 stands for? Probably not. So I'll tell ya. It stands for "water displacement-40". The 40 represents the number of tries it took before the inventor got it right. Yep, he tried 39 times to make WD-40, and then on the 40th try he finally succeeded! A great lesson in never ever giving up!!
