About a year or so ago, I was introduced to Keygolf. Just the ability to define certain concepts, and realise they are measurable, have freed me from past blockages towards understanding.
For example: Building a Belief System
1. Trust (developed in the first year of your life)
2. Knowledge
3. Skill development/management
4. Confidence
These are what's inside a belief system. Carey Mumford is truly hot in this area!
