A fair-weather fan is someone who only supports their sports team when things are going well.
I sometimes go jogging with a neighbor. But he only goes jogging when the weather is good. I go jogging in rainshowers, deep-freeze, blizzards, blistering heat – the weather doesn’t matter.
Why? Loyalty to the intention. A rare and precious concept that will let you achieve anything.
“In good times as in bad times”.
