A fool thinks himself to be wise, but a wise man knows himself to be a fool.<br />
- William Shakespeare
Its true,and I can walk down any street and see people who are so sure they have it right,they are on top of the game,they are wiser than most.Try going into "forbidden"areas of conversation with any of them and see the reaction,a look,a glance of unease,a cutting short of conversation and a swift exit.
If you knew everything you would be Sheldon Cooper.
Very true, but don't let it stop you from learning. The more you know the more you understand how much else is out there to know
very true! as you learn you open many many doors to things you weren't previously aware of
rings true to me there is always something new to learn
