An interesting phenomenon: when faced with truly promising opportunities, most people's reactions are surprisingly consistent—overly cautious.

This is evident on two levels. One is outright passing—seeing the opportunity but shrinking back, ultimately missing out completely. There's a vivid saying for this kind of situation, called the "thumb-sucking mistake"—the opportunity is right in front of you, but you do nothing.

Another, more subtle scenario is knowing it's a good thing but only daring to test the waters with a small amount. Instead of fully committing, you only invest "the amount of a dropper bottle." The consequences of this are often the most regrettable—neither making sufficient profit nor truly validating your judgment.

This is nothing new. Even those renowned for their rationality in investing are often hindered by the same human weaknesses when facing high-certainty opportunities. Overcoming this psychological barrier? Easier said than done. The key is whether you can truly trust your analysis and then act to prove that trust.
