This reminds me, syntactically and conceptually, of the philosophy of parkour I was introduced to when I began practising it during uni.

"Être et durer" - to be and to endure. Train for the future, sustainably, without ruining your body.

And, "être fort pour être utile" - be strong to be useful. Parkour (as opposed to freerunning) emphasizes the goal, movement, reaching or escaping.
