Four core principles that won't make you rich overnight but will help you survive:

First, don't put all your eggs in one basket
A small setback can wipe you out. The core of capital allocation is to leave room for trial and error. Position size is not a symbol of courage; it's a survival baseline.
Second, go with the trend
Don't always try to buy the dip. When the trend is upward, a pullback is a gift; if the trend hasn't broken, don't run. The probability of continuation is always greater than reversal.
Third, take profit and stop loss as your protective charms
Each loss should not exceed 5% of total funds, and each profit should aim to exceed 5%, maintaining a win rate above 50%. The capital curve will naturally rise.
Fourth, don't act recklessly, take a break when needed
Five or six trades a day not only won't make money but also easily lead to losing control. Trading is an art of waiting, not a physical activity.
