Training for the future is about getting good at one thing. Do not be average of 1000 things or a little above average of 100 things. Not even 15 things can be done to become the best in the whole world.
I’ve had a world record, but that does not mean I’m the best at teaching how to break world records. It’s like two completely different things. Several of the mentors I follow constantly say: Do one thing and become really good at it.
So what’s that thing for you?
