Eric Doubt has already established that volunteering is good for business and good for the businessperson’s soul. A great way to volunteer is to become a mentor. Mentors share their skills—personal or professional—as well as their time. While sharing their existing skills, the mentor also has an opportunity to develop new skills themselves, including leadership skills. Mentoring can stretch you intellectually, expose you to the latest thinking in your field, and that can lead to a new energy that permeates your professional interactions with colleagues and clients. On a personal level, the mentor experiences a growth in his own self-esteem and in his overall happiness.
