7. Regret of not being a better partner.
Try not to be jackass in your relationship. I read a story of a husband who wants to divorce his wife, the wife agreed on one condition to spend one more month with her and do the things they use to during the early part of their marriage. He fell in love with his wife again only to realize she has terminal cancer. Don’t be too late to change because you might just regret it in the end.
