Once you have identified potential sources of feedback and mentorship, it is essential to build a relationship based on trust, respect, and mutual benefit. To do this, communicate your expectations and goals clearly, and ask for theirs. Agree on the frequency, format, and content of your feedback or mentorship sessions, and be mindful of their time and availability. Additionally, be prepared and proactive, and demonstrate your commitment and enthusiasm. Before each session, prepare questions, topics, or challenges to discuss, and do some research or reflection on your own. After each session, follow up with a summary, action plan, or feedback, and update them on your progress or results. Furthermore, be receptive and respectful, and express your appreciation and gratitude. Listen actively and attentively to their feedback or advice, and ask for clarification or examples if needed. Avoid being defensive or argumentative, and acknowledge their perspective and experience. Lastly, thank them for their feedback or mentorship, and recognize their contribution to your growth.
