There are times when you need to keep moving forward and not look back. And then there are times (like during a Mercury retrograde) when it's an even better idea to make that apology or mend a rift. Second thoughts don't express a lack of resolve. If anything, they communicate having thought better of an action that wasn't wise to take in the first place. Don't let pride get in the way of doing what's right – especially when there's still time to salvage the situation. Regret is for those who stubbornly chose not to fix things when they had the chance to fix them.
