I've been a long time believer in mentors and coaches. Kim Kiyosaki explains it well in her blog titled Why I Use Mentors and Coaches.
Here's my favorite part of the blog:
My coaches and mentors keep me on track, especially when things get uncomfortable. I know my weaknesses, and I get lazy at times. I have coaches and mentors because sometimes I need people to push me harder than I will push myself.
Mentors and coaches can be the difference between mediocrity and excellence. Professional golfers, the best of the best, have coaches to keep them at the top of their game. It's the amateurs and hackers who think they can do it on their own. It's the same with investing. Mentors and coaches can keep you on track whether you're having a winning day… or a “learning” day.
