learning as a process

the husband shared something really interesting to me and i would like to share it with you guys!

there are generally 4 levels to learning as a process:
1) you don't know what you don't know
oh gosh, you are even clueless over what you dont know!

2) you know what you don't know
ok, better now. you are aware where the gap in your knowledge lies.
but the question is, are you going to do anything about it?

3) you know what you know
i guess >50% of the people should be in this stage.
you are good at your stuff. good for you!

4) you don't know what you know.
you are so good at what you know that its incorporated in your reflexes.
for eg, when doing a right turn while driving, you pushed down the signal for right turn, check your blind spot while your hand automatically start steering the wheel to the right.
all these without your conscious mind knowing.
wow. i want to be at this stage.
time to work harder.

good food for thought for the above?
i really hope so!
