When we want to learn something from someone by asking them questions and gaining their insights, we often use the phrase 'pick someone's brains'. However, there are many other ways to express this same intention. You could 'seek someone's advice', 'tap into someone's expertise', 'consult with someone', 'harvest someone's knowledge', 'utilize someone's know-how', or 'pluck someone's wisdom'. Each of these phrases convey the idea of using another person's experience or knowledge to learn something new or solve a problem. So, next time you need help or guidance, consider phrasing your request in a different, more creative way!
