This is a video response to how to find a mentor. Although this does not answer all possible options, it's a place to start.
1) www.QUORA.com is a wiki community with user-generated content. You can probably find experts or very knowledgeable people in the fields and industries you want to be mentored in. Even if they don't mentor you, their knowledge is available for you to read.
2) SBA Small Business Association has FREE business mentors. You can call or check your local chapter for when they offer free mentoring. The emails and websites can also show you which mentor has the knowledge base you're looking for.
3) FaceBook Groups: commenting on people's posts, and asking questions can help yourself get noticed. You can start liking posts, and seeing who might be the best mentor for you.
4) Blogging: Share what you know. Mentors want to get a feel for your personality and what you already are familiar with. They need to know what you can offer, and if you're open to putting in the work to be mentored.
5) Networking events or organizations: This can happen through word of mouth, or by being invited by people in groups you're in. Have business cards or a few interesting things to say about your work handy. Make a list of what you're looking for in a mentor.
6) Make your own networking event: This is not for everyone, but it can help show people you're committed and value their connection. Meetup.com is also a way to find people like-minded.
7) (Not in video) Peer-consultation group. This might not be the same as having a mentor, but sharing with those in your field and offering tips and support can be beneficial, too. It's something to consider.
