I'd begin the journey by figuring out what you need. If you are in the USA you could go to www.score.org and look at mentor profiles and pick on there. This service is a nonprofit so it won't cost you a penny.

If you're not in the USA I would see what resources are available in your area. I would do the same thing. I find its wise to have a mentor for each area of expertise that you want to A) learn more about or B) don't feel as comfortable.

If you need help finding the right mentor or need a coach to help I'm available as well. I mentor a startup out of Austin/Mexico called OnePay and I'm always interested to help out.

Feel free to call me or connect on LinkedIn.
