Someone needs your feedback, dear Aquarius, even though you may not feel comfortable sharing it. If they are asking you for advice, there is no reason not to offer it. You may fear that if you share what you know, and it somehow backfires, you will be blamed. That is a possibility, but it's not likely right now. If you don't share what you know, they might fail anyway - and then you would truly have something to feel bad about. By caring enough to dispense your wisdom, you are offering the most valuable thing of all.
