Excellent discussion!
I believe the key is being AWARE of your emotions because if we are not careful we can find ourselves annoyed/angry/upset at all sorts of pointless nonsense.
When I say 'pointless nonsense' I am not belittling anyones circumstances but by and large these situations pass and are just occurances in life.
If we spot that we lose control in certain situations we should have an answer ready and the traffic jam thing was a good example.
We can't control the traffic and being angry about it while in the jam isn't going to help. If anything it will make it worse as road rage demonstrates which results in stress and a reduced ability to drive with due care and attention.
Nothing lasts forever and whatever it is that bothers us today will be largely irrelevant tomorrow.
Enjoy every moment. Remember the expression: 'It was awful at the time but we can laugh about it now.'
