Success and happiness is not for those who worked hard, or those who are lucky, or those who are good looking. Anyone can succeed and be happy.
All one needs to do is open the door for your opportunity. Honest mistakes are always innocent when the intent is pure. Carpe diem. Seize the day. Even if your act of seizing the day results in a misfortune to yourself or to others, the mistake is forgiveable. But only if the act was done with the purest of intentions.
