Jack Nicklaus and trading - part 3

A couple of my more popular posts from past years relate to Jack Nicklaus, where I listed a number of quotes from his extensive writings and interviews over the years. 

Below I've pulled out a few more of nuggets of wisdom from The Golden Bear, which again may require some thought on your part, but the underlying message can easily be applied to your trading and mindset:

Are you a Borg or a McEnroe?

Given that this year's Wimbledon is currently in progress, I have a tennis theme to this post.

Any trader who has been profitable over the long-haul has developed a method and mindset that works for them.

Usually, this means approaching the markets in an unemotional, rational state, rather than an emotional, irrational state.

In my opinion that is the way to be, but that statement is not complete. Behind that, it is quite possible to go through emotional ups and downs on a daily basis and be successful.
