It’s easy to think we are special when in fact we are not. Nothing separates you from me, except the actions that we take.
The best underrated action: limit your options. Make it impossible to waste focus on as many things as possible outside your mission. For IOS users: ‘screen time’ in settings. Set your social media and games to whatever time limit you want (less is better). Have your friend (or stranger on the street) put in a 4 digit pin. Voila! You are now incapable of wasting excessive time on your phone.
Look for ways to limit options and you’ll be more likely to do the right things.
