This is a great quote! In poker, the ability to read your opponents and identify weaker players is crucial for success. It's important to always remain aware and observant at the table, rather than getting too caught up in your own ego or assumptions. Additionally, it's important to only play hands with good potential for winning, to play according to the situation, and to study the psychology of the game. Playing with better players, learning different types of poker, and watching professional games can also help you become a better player. But of course, the most important thing is practice, practice, and more practice. The more you play poker, the more experience you'll gain and the more chances for success you'll have.
