National Mentoring Month.
You can make a fundamental difference in the life of a young person. Establish a path based on what you have learned first-hand in your own life, regardless of where you are in your career. Or you can answer the call for mentors nationwide through a system like the one at the mentoring.org website. There, you will find suggestions you can scale up from occasional work involving youth in your home area, all the way to starting your own local program.
Your commitment and guidance can be the driving force to your mentee's future success and their willingness to reach back and help someone else. You might even find that helping a young person find their way has the echoing effect of helping you strive for more, as you begin a new year with new goals.
