The unmistakable process of learning.
Every time you make a wrong move and you contemplated the next time it becomes automatically ingrained in your character.
Every time you make a mistake the voice creates self judgment and low self esteem. it becomes unstable which only makes it hard to learn from the failure, the voice subside and you get chance to reconsider. and handle the situation differently from next time.
The quality of contemplation makes the difference in the response in next time, and that is process of learning and change.
The major challenge is the voice becoming unstable and me acting on it, if you know that it is going to happen and keep your focus on the problem, you can win. the second is the quality of contemplation and dignosis and root cause analysis, the challenge here is it requires more enegy to do so and not taking actions feel sweet hell.
