That is questions that provide a different perspective, stimulate not only the recipient but yourself.
Questions that flip the perspective, provide more insight and potentially shine the light on new opportunities.
Get beyond the standard questions and delve deeper. You not only owe it to yourself but to whom whose precious time you have requested.
You’ll know you’re getting it right when you hear “I’ve never heard it put like that” or “I’ve never thought of that” or most importantly “I like the questions you ask”.
You see questions aren’t give and take, the right question can give to both parties.
