Just jump in.
You know that moment, your feet are in the water, it’s cold and you know jumping in will be uncomfortable. The waves start to splash higher to higher, each hit a reminder of how cold the water is.
All you have to do is jump in. A moment of cold splash before you get used to it. But’s unpleasant and so you stand there. Cold wave after cold wave
Finally you jump. You squirm around a little to warm up to completly forgot you were cold at one time.
This is a reminder to myself mostly to just jump in. Stop tourtoring yourself with cold waves. Be uncomfortable briefly, it’ll pass.
