What is once a player always a player?

"Once a player, always a player" is a saying implying that someone who has a history of being a player (often used in the context of dating multiple people simultaneously or engaging in short-term flings) will always be this way in the future. The saying suggests that this behavior is deeply ingrained in their personality and is unlikely to change. It also implies that someone who has a reputation as a player may struggle to form long-lasting, meaningful relationships due to their tendency to prioritize their own needs over those of their partners. This saying is often used in a negative context, and people are advised to avoid getting involved with someone who is known to be a player. However, it is important to note that this is a stereotype, and people can change and grow beyond their past behaviors if they are motivated to do so.
