There is a difference between happiness and joy. Some have the definitions flipped, so I'll not try to define them. It's not important which is which. One is a result of circumstances. If something bad happens, like you get a flat tire, then you're in some negative state of emotion. Most people are ruled by this, and since most circumstances are out of our control, we spend a large portion of our time in some state of unhappiness or frustration. The other is trying to be at peace. If you're basically at peace then the flat tire doesn't ruin your day. It's just something to deal with. Things happen, you deal with them, life goes on, and you're mostly thankful for what you have.
