Consistency and moderation over intensity

Yesterday I came across this sentence. It was about to run a marathon but in the end we can deduce to most of our life.

else why live?

Oh, I think we all need a bit of intensity.

In moderation.

all things in moderation, including moderation

Everyone's life is different, this is something that I think definitely works though. I understand and agree with what the posters before me said as well, if you ever want to finish that marathon you have to pick up the pace every once and a while. Sprinting at the beginning with the idea you'll make the ordeal hard and fast usually just results in you passed out on the side of the road though.
