I think a good question to ask oneself is in a current relationship (or the last one, if single), "where am/was I selfish" or "how am/was I selfish?".
One the biggest culprits in our society in terms of relationships, is selfishness. Love is 100% giving, not expectations. The trick in our culture is winning the lottery where the other person is also transitioning to selflessness at the same time you are.
Selfishness is genderless.
