You shouldn't run before you can walk.
Same goes for that clown from Caramel Bikes (which is actually worse, because has no idea whatsoever about bicycles and their components).

If I decide to become a surgeon, because people are willing to pay good money to have their tits enlarged or appendixes removed and I'd like a piece of action in the field of medicine, I am not going to set up surgery on Monday. Or am I?

Have you ever seen how the number of avoidable, negligence related deaths in hospital spike every August; just when all the bright-eyed, eager newly qualified junior doctors leave medical school and take up paid positions in a hospital. Hell even consultant surgeons, with years of experience, who everyone expects to be faultless make mistakes. If you are using medicine as a metaphor for this then; really good doctors are not the ones who do not make mistakes, as there is no such thing, but the ones who make mistakes assess what they have done wrong and how they can prevent it from happening again.
