Being a nice person and caring about others is important, but if you are not careful you become a doormat, and then resentment alienates you from the very people you were trying to bond with. You resent them and they lose respect for you, because they don't need to show any and in relationships people are naturally lazy. Why would they put in any effort, when you seem content to accept them without it?
I'm a mumsy sort of woman, always fussing and trying to keep the peace. I tend to go along with things that others want to do, rather than pushing my own ideas too much...But I have a limit. At my age I've had a chance to learn that being a martyr is irritating for me and frankly a bit ugly for others to watch. It's better to have the courage of your convictions and only to do what you are happy to do, or give what you are happy to give freely. Then you are being true to yourself and honest with those around you.
