Barry Schwartz, writing in The Paradox of Choice makes a compelling argument – to my mind – for cutting down the options.. One paragraph on the subject of life and partners grabbed my attention.

.. inevitably, you will find people who are younger, better looking, funnier, smarter, or seemingly more understanding and empathetic than your wife or husband. But finding a life partner is not a matter of comparison shopping and ‘trading up’. The only way to find happiness and stability in the presence of seemingly attractive and tempting options is to say, “I’m simply not going there’

…Knowing that you have made a choice you will not reverse allows you to pour your energy into improving the relationship that you have rather than constantly second-guessing it.

The grass is always greener – we need to learn where/when to stop looking!
