“Everything starts somewhere…”
Though knowing where depends
On what you mean by “start”
Or “everything”.
Something starts everywhere,
The chain of consequence
Cannot be predicted
Precisely.
Freedom to make a choice
Freedom to take the chance
Is meaningless without
Consequence.
Forge your link in the chain,
Own neither more nor less
Than your contribution
To history.
Terry Pratchett, Hogfather
