Next time you rinse off, do this:
Standing right under the showerhead, gradually increase the hot water. When you can’t handle it anymore, turn the temperature all the way to cold (and brace yourself). Wait to stop hyperventilating before turning the water off.
Do this every day. Not only is it refreshing, but it’s also a daily reminder that for many things, getting past the initial resistance is the hardest part. 🚿
