Am i too good?or too bad?

Some says that i am too much good helping to my friends.I never say no to them but for me i am not.I just want to help my friends if they really need me.For me helping to other people it feels good and it is like helping to my self too.Mostly if i help my friends i always think that if i am in their place,I'm sure that i will be very happy to see that there is one person who is willing to help me.Though i never expect any exchange or rewards, but i heard that it is too much because there are other friends are try to take advantage of me.As of now i didn't notice yet!But hope it will not come.Because maybe i am good person but i am very bad if i get mad too:-)
