We must all consult doctors,lawyers,bankers and other specialists to help us, but view experts with a jaundiced eye.Trust your own knowledge and instincts.When something sounds fishy,ask,"Says Who? Where is it written?" Is the expert there to help you-or to attend a bigger client, to please the boss, to get personal visibility or to win a better job? Never assume that so-called professionalism will protect you.
-David Mahoney

We should be careful and discriminating in all the advice we give; we should be especially careful in giving advice that we would not think of following ourselves.Most of all,we ought to avoid giving counsel which we dont follow when it damages those who take us at our word.
-Adlai E. Stevenson

The true secret of giving advice is, after you have honestly given it,to be perfectly indifferent whether itis taken or not and never persist in trying to set people right.
-Hannah Whitall Smith

Commanders should be counseled,chiefly,by persons of known talent,by those who have made an art of war their particular study, and whose knowledge is derived from experience;from those who are present at the scene of action,who see the country,who see the enemy,who see the advantages that occasions offer and who like people embarked in the same ship, are shares of the danger.
-Lucius Aemilius Paulus,

Never trust the advice of a man in difficulties.
-Aesop
