We always complain that we can't catch the golden dog, and when we see it, we hesitate to act? When we do act, we buy less? After buying, we sell too early?
While you complain, how much have you invested in this? Will you study once it's out? Can you make quick decisions? After failures, do you go back and analyze the reasons?
When the market is poor, are you patiently waiting for the next opportunity or continuing to complain that fate is not giving you a chance?
Sitting quietly, reviewing, being calm, and patient.
