Here is how to encourage business and personal friends to give you their best advice. Some friends are deep thinkers who have lots of wise counsel within them. One way to draw it out is to simply ask questions: "You are my friend, what do you think is the best way for me to handle this problem?" Or ask: "What do you think I should do now? "Here is my situation & I wonder if you can help me?" In short, you use "kindly persuasion" as a way to ask for them to share their wisdom with you.
