what about the reinventing of the wheel?
I see, its a figurative speech, using the wheel to illustrate my point. As you know, the wheel is a simple invention thats been made many years ago, so if people says that they don't want to learn from other people's experiences and mistakes, and that they want to experience the pain first hand, then I use this phrase " I'd rather not re-invent the wheel" meaning, I'll use the wheel that's been invented long ago, and make something else more advanced and sophisticated, got it? That equates to me saying that I will use other people's lesson in life, to apply in mine, so I don't have to go through the same process that they went through, its not very efficient to lead life that way, IMHO.
Don't mean to make this sound like teaching you to suck eggs, its just to clarify your questioning.
