Many top business leaders credit having the guidance and support of a mentor as a key to their success. Mentors can help you identify and achieve career goals as well as your strengths and weaknesses. This can lead to increases in confidence, job skills and salary. A mentor can push you and give you the tools to negotiate better pay, ask for a promotion or consider new job opportunities. Newbies to the workforce aren't the only ones who can benefit from mentorship — you’re never too experienced to learn from others.
