Restraint and abandonment
There's a fine line between holding back too much and not letting go enough. When do you give it all away and when do you keep a little in the tank?
I was listening to Malcolm Gladwell on the Tim Ferriss show and he commented about how runners train with restraint, and that it's the hardest thing to do to get elite runners to hold back. That they don't need to be pushed - they need to be held back mainly so they don't hurt themselves.
This has me thinking about where I need to give more and where I need to give less. Where to restrain myself, and where to let it all go.
