Why perception is the key in trading (and in any) performance

This is a great post on New Trader U: Transform Your Market Performance With This Simple Shift.

The key points: 
- Life is a mirror that casts back to us our own reflection!
- An openness to challenge what we think we already know about the world.

So we continuously have to challenge the way we perceive say the same price action in different market circumstances. Perhaps the best way to start is developing competitive scenarios based on the same setup. The challenge is to treat those scenarios independently. In other words you have to have at least three independent mindset and you have to treat them or let the exist without influencing each other. You have to be able to thing bullish, bearish and believing that market is in a sideways mode.
