Fortune knocks once, at least, at every man’s gate. (Dictionary of English Proverbs/Thomas Preston)
We all have opportunities. Some people have more opportunities than others. All of us have at least one opportunity. What if we miss the opportunity? Maybe we only have one opportunity for that one thing. However, that does not mean another opportunity does not also come our way. Maybe the second opportunity is not as good. Regardless, we all would be wise to keep alert for opportunities and be ready, willing, and able to take advantage of those that come our way.
