Advice and reprehension (blame and reproof) require the utmost delicacy; painful truths should be delivered in the softest terms, and expressed no farther than is necessary to produce their due effect.
A courteous man will mix what is conciliating with what is offensive; praise with censure; deference and respect with the authority of admonition, so far as can be done in consistence with probity (sincerity, integrity) and honor.
The mind revolts against all censorian power which displays pride or pleasure in finding fault; but advice, divested of the harshness and yet retaining the honest warmth of truth, is like honey put round the brim of a vessel full of wormwood.—
Even this, however, is sometimes insufficient to conceal the bitterness of the draught. -- Percival
I had opportunity to use this outline for advice just recently, and I am so glad I did.
So practicle. Would that I had followed this outline many times in the past.
