During your career, whether that be long or short, you have learned things..many things..along the way. With that knowledge comes responsibility, the responsibility to pass on your learnings. The more important your knowledge, the more important it is to share. So look around and identify those that could benefit from you and what you know..students just starting out, recent graduates new to the working world, colleagues breaking into a different industry or new job, peers from a different team or your regular working team. Then proactively reach out to share the insights from your experiences without expecting anything in return.
