There are two forces at play here.

Agility and persistence.

Agility and strength make us go fast. Persistence gets us to play long.

There are those among us who can go fast. There are others who can play long.

But if you want to play fast and also play long then you need to avoid death (burn out) by going too fast – so that you can play long and go far.

It is ok if you are not a natural at both. You can be a natural at one and acquire another skill by application of your will, body and mind.

And, all this assumes that talent, opportunity and current reality is the same for everyone which is rarely the case in real life. So, play fast or long but do it while keeping the other realities of your life in perspective.
