I see that most of the successful people in the world had mentors that contributed to their success. How do I find one if its so important?

The best mentor and guide for a person is himself. you just need to be aware about First Mover Advantage in your external environment.
for more, i am just a call away.

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.

First make sure that it is really important for you.

I would suggest some more 'soul searching'. What and Why and Who questions are good places to start. Like in most questions of this nature.

What: What do you really want? What kind of lifestyle, business success? How would you measure these?

Why: Why are these objectives important to you? What is the big deal?

Who: Who are the people you want to serve or market to? Who are the kinds of people you want to have on your team? Why?

Then find the mentors who have helped people achieve the results above.

Mentoring is a serious relationship - it should be. It is a partnership that is sacred - not in a spiritual context but in a honoring partnership context. The mentor usually gives of her or himself in terms of time, energy and opportunity cost. He or she typically wants to see you become successful - usually they operate at a higher level of a vision of helping people like you so that their view or vision of the world can be fulfilled. You have to demonstrate your clarity first or a very committed attention to discovering that clarity before any worthy mentor takes you on.

Thanks for such brilliant question. It's a matter of importance to find a mentor whose life and achievements are in line with your prospects and field cause it'll help to direct and channel you better towards reaching your goals, like myself as a Human Relation expert i have mentors like Dale Carnegie and other human relation expert like myself whose biography and books i have read and they have given me a-lot of insight on how to handle people and my relationship with them.
So first of all in finding a mentor; you have to find someone whose life appeals to you and who falls in your line of interest, goals, field of expertise or moral standard in general. Then research about the person, ask questions and gather as much information as you can about the individual, if he or she is pretty much alive or active you can try reaching out to the person as that would be another step ahead of the game...
