Have you heard of Jocko Willink? He's a former Navy Seal turned author who doesn't take no for an answer. He served in the Iraq War and has been through the toughest training imaginable. What's the one habit he's consistently kept?
Getting up at 4:30 AM. Why? Because you get a head start on the day. Why wouldn't you get up early if you can get a headstart on other people?
If you get up early, you have the peace and serenity of complete and utter free time without distractions. Business doesn't happen at 5 AM in the morning. You can look after yourself.
Do a light workout, drink some water, read, write, create, learn, or go for a run. Taking action early and creating a routine sets a strong tone for the rest of your day.
