If I had known this, why did I do it in the first place?

If I had known that there would be such serious consequences, why did I do it in the first place? People should not do things they regret. Once you have the right opportunity, you should seize it. Don't wait until it passes before you regret it. By then it is already too late. Remember one sentence, before doing anything you should consider the consequences. Waiting is better than doing it wrong.
