First, very sorry you lost your wife, may she rest in peace. I can't say I know how you feel, but I can imagine and I hope you are doing well considering this loss.
Truer words have never been spoken. All too often we are so wrapped up in our own little world that we fail to notice what is going on around us, and we take all for granted. I thank you for these words of wisdom, I shall take heed. Thank you.
