The most stable mindset for investing is contentment and securing profits. Don't chase massive market rallies or gamble on extreme price spikes. Earn profits from opportunities you understand and can hold comfortably.

In execution, avoid prolonged battles and don't chase the beginning or the end of a move—trade only the middle section, the fish body. Take profits when ahead. Avoid chasing rallies and panic selling. Stick to your profit-taking plan and don't let price swings control your emotions. Build big wins by accumulating small wins steadily, preserve your principal, and profit consistently—this approach is much more sustainable than pursuing overnight riches, and it brings peace of mind.
