Flow comes from liberating the mind.
The best thing we can do for ourselves is training our body, mind, and spirit in that order.
Not too long ago, I was helping out an old friend teaching some schoolkids how to fight with swords.
Not lightsabers or anything toy-like, but real swords made of steel by a blacksmith according to the original European craft and design.
You may not know this about me, but when I was younger, I spent more than ten years of my life training with European swords as a martial art.
I was pretty into it and reached a relatively high level, before I left it behind for something else. So when I picked up a sword to help my friend, it was the first time in 12 years, I held one.
