Worry/Regret over nothing, if you've been worrying/regretting over anything before now. Because, worrying/regretting over and over again is as good as adding/rubbing salt to/on your own injury i.e. each time you decide to worry/regret over anything, be it your past life, mistakes, failures, disappointments and things like that, you are unknowingly worsening the case/matter in question. Yes, of course, that's just what you will end up doing to your own self/the case/matter involved. Although, I do know that some issues/matters do seem worrisome/regrettable like loss of job/opportunity. But regardless of that, rather than worrying/regretting over that/any other thing, pray about the/your case/issue. For surely, prayers can change your condition /case for the good. So, dare to worry/regret over nothing hence forth. Instead, pray over anything/everything.
