“If only I’d known…” is something that many people say on daily bases…
However, there is really no such thing as “If only I’d known…”
To say that… it’s just that the results of the situation is not the outcome that oneself expects…
Nevertheless… what’s happened has already happened… and what’s done is done…
To some extend… “If only I’d known…” is an excuse for not wanting to take the responsibility of the decision.
Needless to say… it’d be impossible for a person to make right choices throughout one’s life…
But… if mistake does happen… the person can reflect and learn from the mistake and not repeat it… it is better than just saying “If only I’d known…” and does nothing about the mistake…
