It can be hard to throw away a favourite old coat. You look around for a new one, half heartedly, stick with the old one for one more season. It is worn thin, the lining is torn, it really doesn't serve the purpose of being a coat any more, beyond repair, yet it is comfortable, comforting.
You know the coat has to go.
You buy a new coat. It's satisfactory, does what a coat is supposed to do, keeps the rain off, the wind out. It isn't your old coat.
One day, one ridiculously cold day, light drizzle, wind off the ocean that could cut you in half, you are warm, dry and happy in your new coat. You congratulate yourself on buying the new coat, for making your own life so much better.
One day, you are preparing to leave the house, grab your new coat off the hook, it slides on like an old friend, it has become your old coat.
The last few weeks I've taken on a new way of thinking. It is uncomfortable. It doesn't fit like my old way of thinking. The new way of thinking is serving me well, like a new coat, it does everything a way of thinking should do. The old way was comfortable, but it had ceased fulfilling the purpose it was designed for.
This new way of thinking still doesn't feel like my old, favourite coat. One day it will. By then it will probably be time to replace it.
