We give advice by the bucket, but take it by the grain. – William R. Alger

When we ask advice we are usually looking for an accomplice. – Charles Varlet de La Grange, Pensées, 1872

It is easy when we are in prosperity to give advice to the afflicted. – Aeschylus

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