How to be a good mentor without being frustrated?

Mentoring can be incredibly rewarding, but it's a responsibility. I enjoy doing it because I have seen how real estate has changed my life.

I want to set clear expectations at the beginning of the relationship. I have many quality friends so really only looking for a professional relationship. I realize people are at different points of their real estate journey. I like to see people grow and I enjoy celebrating others investment wins and trials.

My problem is that I feel a lot of people waste my time.  I dont want to meet for coffee because my schedule does not allow for it.  I dont want to answer questions that can be easily searched on Google. I need to quickly find out how motivated the other party is to accomplish their goals.  It seems I am often more interested in their success than they are in their own accomplishments. 

When I think about my journey it took time. I didn't always follow through on what I knew I should be doing.  Sometimes I just needed someone to encourage me or correct me.

Question:  what have you done or not done that helps to develop a good mentor/ mentee relationship?
