Finding a mentor is difficult only because you want to find the right one, with the right values and ethics. 

After you ask your mentor for help, what is your responsibility?

Your mentor will give you the most priceless possession he/she has … their time.  And you should regard that as if it were gold. 

Respecting that possession demands that you demonstrate some follow-through on the suggestions made by your mentor.  You can disagree and have discussion - which creates learning experiences. But when the meeting or discussion is over, your follow through is the payment your mentor expects.

Anything less will dampen the enthusiasm and desire to continue to participate and you may have lost a precious gem for a lifetime of learning. 

Respect time and follow through!
