I like the points in the article, having been a big fan of Tony Robbins (Awaken the Giant Within) materials, they do help one develop expectancies for success.
Re making mistakes, I'm sure I've made all of them many times myself.. as always learning from them and standardizing the 'lessons learned' to fit the current situation is always helpful.
I've found that "experimentation is the key to success" in many of life's ventures. (dating somes to mind lol) In trading, experimenting heavily with various indicators, trading styles, etc then test out what seems to produce the most consistent results for each trader personally, seems to be a solid course of action.. and continue testing, to stay flexible with whatever type of market conditions you're seeing.
