Mentor–mentee relationships thrive on clear, respectful communication. Differences may arise, and although they can be hard to talk about, being able to discuss them openly through professional dialogue is a skill we can all continue to develop. #Mentoring

When setting goals, we often focus on achieving milestones like a PhD, job, tenure, or promotion. Those are great goals but they’re not enough. We also need to think about: -Why we’re pursuing that goal -What specifically we need to do to succeed -The values we will follow as we do the work

Leadership skills are similar to research skills - we aren’t born knowing the best approaches but we can learn. And just like learning how to be a researcher, growing as a leader involves making mistakes, listening to feedback, and improving over time.
