You can select as many categories as you wish, but keep in mind the more selective you make your search, the less likely you will find someone. If you need advice in marketing and finance, you will get ONLY the mentors who have indicated experience in both areas. Your search will give you the email address of the individuals and a quick glimpse at what experience they have. You can review their mini-resume and decide who you would like to be mentored by. Remember to keep your contact with your mentor on a professional level.
Mentors have careers, families, projects and their own deadlines and responsibilities.
Monitor the time and the amount of contact you have with them and show appreciation whenever you can. The only reward mentors get is seeing the positive changes and improvements that occur based on their involvement.
