Conclusion
Finding mentors and becoming a mentor are career-long endeavors. Doing so pays valuable dividends in career growth, personal networking, and professional development. If you have not identified those people in your life who serve as mentors, take some time to build that list.
Also take the time to identify those who have routinely approached you for input. Whether the label of mentor is used or not, that is what you have become. Take the responsibility seriously. The positive career impact cannot be overstated.
