If you don't have a firm logic, don't buy. If you don't have confidence in yourself, don't buy. If you are easily influenced by others, don't buy. If you can't take responsibility for your own decisions, don't buy. Investing is never a game of following the trend, but a battle of cognition and conviction. The market will fluctuate, and prices will fluctuate, but you must understand: You are not buying based on news, but on your logic; You are not holding onto a price, but on your conviction. There is only one prerequisite for buying: You are willing to take full responsibility for it.
