Seeking Mentor

Well as I been talking about I have a huge interest in becoming a CRNA. I haven't really found anybody just yet to be a great mentor for me but i hope i find one soon! But even though i might not have a mentor yet i do have in mind of a get mentor that i picture which would be a mentor that loves the job they do and have an amazing work ethic that anyone could admire. Some questions id like to ask a mentor would be what is the hardest part in being in this field? What type of person will succeed in this line of work?
