When I do new things, it feels like I make a lot of mistakes. However, I only make a mistake once, I don't repeat them (most of the time). It always feels good coming away knowing more than when you started, if everyday could feel like you're working towards something bigger than just existing, my world would be a better place.
Read something that the British Army use in their training;
"Pain is Weakness escaping the body"
I like the way that sounds.
