One of the best ways to evaluate the effectiveness and impact of your networking and mentoring activities is to collect feedback and evidence from the people involved. You can use various methods, such as surveys, interviews, testimonials, or portfolios, to gather information about the benefits, challenges, and outcomes of your interactions. For example, you can ask your network contacts how they benefited from your advice, or you can ask your mentees how they improved their performance or confidence as a result of your support.
