Speaking from expierience yes. I was burned far too many times, mostly by family. I always thought family you help one another, but after thousands of dollars later and a broken heart, you have to draw the line somewhere.
The question is, what is "too" nice? The implication is that there is a limit to niceness, a boundary condition for exceeding the good one can do for another. Mother Theresa showed that there are no practical limits to the good one can do for another, if the will is there to be vulnerable and open to God working through us. The Dali Lama has also shown the patience required to undo injustice non-violently. Martin Luther King demonstrated the will required to confront prejudice and injustice, and to do it non-violently. Ghandi showed us how to persevere with the quiet journey of the soul in the face of a materialistic and deterministic world, and we have yet to see a leading figure in the green revolution, but I suspect there will be one. Do not be weary in well-doing, because it both does good for the one you serve, and gives an example of good works for others to follow. Do not faint, and persevere, for the victory does not belong to the swift, or the strong, but to the steady.
yes there was a time when I was too nice and I could see how so many people were holding it against me. especially my ex. i dumped him anyway and i'm not nice anymore. this might be over correcting but I don't care.
Yes. People who are too nice will get stepped on or taken advantage of in life. This does not mean that you have to start being a bad person, just learn when you need to stand up for yourself or recognize when others are trying to take advantage of you. It's a sad fact of life but definitely true.
Yes definitely, my Dad used to help out loads of people and all that and then one day he just couldn't do it anymore (personal stuff) and almost all of the people he knew wanted nothing to do with him, most of them were supposed to be his friends, makes moi angry just thinking about it.
Anyways that's why I am the semi selfish sorta bloke I am today, I'll still help those in need, but on the streets I come across as a bit of a rude @rsehole, which is why most people don't ask me for anything lol.
It's always good to be nice and helpful. But unfortunately there are those people who will take advantage of situations. This is where Boundaries come in. There are several good books on Boundaries and how to make sure you are not being used.
