"I dont know" syndrome

I have got many feedbacks ( not only present).., but in past also.., that i dont have to be always humble and honest :)

i have to present myself in a good way - so that i dont need to say - "idont know" always expecially to juniors.

i have tried... but always i will come back to "i dont know" as that is the easiest way out.

perhaps i have got a remedy for that.. i should fight on the core-issue :) i have to know, what i should know.

perhaps i should know the things i should know better than any one else. so my integrity will be preserved !!!

And the things " i dont know".., i will say "i dont know".
