Bull markets are never about how good you are at trading, but how few mistakes you make.

Once the market enters an upward cycle, the direction itself is working to make you money. The more you tinker, the easier it is to give profits back with your own hands—drawdowns are often not due to misjudging the trend, but because of overtrading.
The real difference-maker isn't who guesses short-term moves better, but who can endure more: fewer position changes, less impulsiveness, less self-conceit.
Many people lose not because of their ability, but because they can't "hold back."
Retail investors' scripts are always the same:
Fear of missing out when prices rise, becoming more anxious as it goes up;
Fear of collapse when prices fall, cutting more as it drops.
