I'm not as selfless as I used to be. There's been some people who have took advantage of it and I had to teach myself to be selfish and stick up for myself. There's nothing wrong with being selfless or selfish, it's just you shouldn't be on the end of the spectrum with either of them. There needs to be a balance between the two.
I'm very selfless. I tend to put others before me sometimes. It can be a good and bad thing, but I always aim to make sure the people around me are happy.
