@jasonleow - three hacks that work well for me.
1. Get some exercise - go extra hard on the bike or run or weights to push into the sweat zone.
2. Ear plugs - all the traffic noises outside startle me - these help calm the lizard brain.
3. Get up early - by getting up early, you'll be ready to go to bed early - when you go to bed early, if you need to, you can sleep more than you think you need
As I spend much of my day learning and practicing new things, I need the extra sleep to consolidate my learning. I find that waking up naturally in a well-rested state does wonders for your emotional well being as well. When I don't get enough rest, my fear and anxiety about life is high. When I'm well rested and willing to go back to bed or lay down to recover properly, I'm much more calm and confident.
I double-down on sleep by getting up earlier than the rest of the family and the city for that matter. ( up at 4:30 am this morning ) When I get these early mornings to myself, I'm done with my work before most people start their day. That just feels like a secret super power.
