Just repeat this to yourself on a daily basis:
Do I have a strong foundation that helps me have an “edge” where the odds are in my favor?
Am I chasing stock moves or using my “edge”?
Can I execute my strategy? I don’t buy/sell stocks, I execute my strategy — the strategy determines which stocks to buy, how many shares to buy, how much risk to take, and when it’s time to sell. I simply execute the strategy without fear or emotion.
I am in a strong mental/emotional/financial state where I can make good decisions — not emotional decisions.
