Act!

 Let no act be without purpose 

Marcus Aurelius - pg.15 : Stoic 6 Pack

Like a fire lays hold of what falls into it

A small spark would have been extinguished 

but when fire is strong , it soon appropriates

itself to the matter that leaped on to it

And consumes it, 

and rises by thus very material

Let no act be done without a purpose

(make purpose the very fire within)

and that shall make a material for itself

out of which opposes it!

 

My note:

Nassim Taleb says a similar thing in his book  Anti-Fragile

Wind extinguishes a spark - timid flame

but the same wind energizes a Wild fire

such that the Fire shall make a material 

out of the opposing force such as the Wind itself!
