I understand what you're trying to say here but it's not what the parent was talking about. Everyone's circumstances are different and that's OK.

You don't have to give away your money or possessions to be nice - all you have to do is smile at someone. Say hello. Ask the shop clerk how their day is going and mean it. Bring cookies into work. Let someone merge in front of you on the road. There is, if you look for it, always time and a way to bring a little bit of joy to the people you see in the world. If we all realize this, life becomes a lot more fun for everyone.
