Don't measure yourself by what you have accomplished, but by what you should have accomplished with your ability.
John WoodenWhat it comes down to, I believe, is that mentoring often involves telling people what they need to hear, rather than what they want to hear. When you are able to be humbly honest with someone about a situation with which you have personal experience-even if you risk angering or hurting that person-you are offering the most valuable gift of all.
