What masculine qualities are useful for women to have?

It's easier to deal with. Most women take everything seriously. However, if some things are perceived more easily and not so categorically, then life will become easier and there will be a smile on your face more often. Hints are not needed. Oh, women love to give hints and expect men to understand them. No, they won't understand! Therefore, speak directly to men about what you think or what you want. Problems out of the blue. No need to make a molehill out of a molehill every time and every day. Most relationship problems happen precisely because women exaggerate the extent of the problem.
