Blessed the geniuses who know / that egomania is not a duty.
Your thorns are the best part of you.
Egotism is usually subversive of sagacity.
In a poem the words should be as pleasing to the ear as the meaning is to the mind.
the sea is a collector, quick to return a rapacious look.
The weak overcomes its/ menace, the strong over-/comes itself.
