Is fear the greatest threat to happiness?
I sometimes wonder if fear is perhaps the strongest factor that detracts from our happiness. Particularly worrying about things that have not yet come to pass. Thinking ahead is often prudent, but rehashing concerns over and over is like living the feared event repeatibly.
What do you think?
Any ideas how to avoid this?
Are some people just more pessimistic?
Is there an optimum balance between concern for the future and living in the moment?
