Lily - it's from an old adage (and not necessarily something I agree with):

"Them as can, do; them as can't, teach and them as won't, teach teachers."

It basically divides the workforce into three groups. There are those good with physical abilities (the 'do's), some are good with mental abilities (the can't dos) and some who have no particular merit but do stuff anyway (they usually end up as middle management - the people who are responsible but don't actually do anything sensible or practical).

I'm a doer. I can do things, but there's no way I could teach someone else to do it. I can impart information but I cannot interest them and make them want to learn more. My friend Ian is a 'can't' - he does stuff, but he can also explain what he's doing and make it sensible and intelligible for technical morons like me.

The world needs both the 'doers' and 'can'ts', it's the 'won'ts' that are maybe not so useful (Remember Douglas Adams' Golgafrincham "B" Ark?)!

Hope that makes you feel better?
