Fortune converts everything to the advantage of her favorites" is a quote that encapsulates the idea that luck or fortune often seems to favor those who are already favored or privileged in some way. It implies that those who are in favor, or those who are already successful, tend to have things work out in their favor, even in situations where it might not seem likely.

This quote suggests that fortune is not random, but rather selective and biased. It personifies fortune as a being who consciously chooses to bestow her favors on those she prefers. This could be interpreted as a commentary on social inequality, where the rich get richer while the poor remain poor.

In today’s world, this quote could be applied to the concept of privilege. Those who are privileged in some way, whether it’s due to their race, gender, socioeconomic status, or other factors, often have more opportunities and face fewer obstacles than those who aren’t as privileged. This can lead to a cycle where the privileged continue to benefit while others are left behind.

In terms of personal development, this quote could be a reminder to be aware of the advantages and opportunities that you have been given in life. It could also inspire you to work towards becoming one of fortune’s "favorites" through hard work, determination, and making the most of the opportunities that come your way. However, it should also prompt reflection on the importance of leveling the playing field and providing opportunities for those less fortunate.
