Whatever we do during the non-trading day is training for what we will be like when we're trading. Everything we do trains us for something. If we are scattered and disorganized in our personal lives, we are building those qualities and will enact them in our trading. If we fail to make efforts outside of trading, it won't be surprising if we don't follow through on goals written in our journals. Bella's point is that we become better traders by enacting the qualities in our personal lives that will make us better in financial markets.
