People who enjoy doing good deeds do this out of the goodness of their heart and never say a word about it. It is second nature to them because it is part of who they are and they are not looking for praise from anyone.
People who do good deeds for others and tell other people about it are doing it for self-gratification. They need everyone to know all the good things they have done they are looking for praise.
You should never brag or boast when you do something nice for someone if you do then you are doing it for all the wrong reasons.
