Take a cold shower. Seriously. Do it. It will wake you up, shock your system, and make you feel alive. It sounds so simple but the best things tend to be so. Next time when you are taking a normal shower, turn the hot water off and stand under the faucet for 90 seconds. And breathe with it. That’s it. We live in such comfort it is important to put your body and mind through small tests that you can overcome.
