To me, soccer is the metaphor of life. It represents life the way most of the world sees it: achievements being due to hard work, but impacted by uncertainties.
Hi Daniel, I think this has too much telling and not enough... poetry. In a short essay like this, you have to choose words that really impact the reader. To turn this into poetry, choose a real PURPOSE... a specific experience you want to provide for the reader. The sentence above, about soccer reflecting life as most people see it, is very good! It is memorale and significant, not like the mundane stuff about when you started playing soccer or "played in many successful clubs." Don't waste any words! Let it all be for the reader's experience of _______.
Of what... excitement about going deep into something meditative, like soccer.
