Asking great questions is a perfect way to build a relationship. But the key word here is “great” questions. Never ask a mentor a question Google can easily answer for you. Carve this in stone. Scrawl it in blood above your desk. Get a tattoo of it. You can learn the basics of any subject on Khan Academy. And you should have already done all that work. Asking your mentor a question is like a power up in a video game. Don’t waste them. Use them when they’ll really count.
