"I'm not a very good advice-giver"

This quote by Juliana Hatfield implies that she does rule out herself to be a trusted source of advice. This might be interpreted in a few different ways. It might suggest that she does not feel qualified to give guidance, or that she does not have the experience or understanding to offer handy guidance. It could likewise indicate that she is not confident in her ability to offer recommendations, or that she is not comfy giving recommendations to others. It might also be interpreted as a humble declaration, suggesting that she knows her own restrictions and does not want to provide guidance that might be potentially hazardous. Whatever the case, this quote suggests that Juliana Hatfield is not a person to rely on for recommendations.
