The retrograde Mercury in Sagittarius can trigger an onslaught of opinions that would be better left unspoken. The tendency, under this planetary influence, is what is known as 'inserting one's foot into one's mouth.' You may feel the urgency to express yourself, feeling that your input is badly needed.
However, what can result from your high-minded comment is a high-volume response. Although you may feel the need to address a particular matter, you may in fact, make things worse. Generally speaking, your judgment isn't quite on the mark.
You could be overly optimistic, expecting your listener to embrace all of your views wholeheartedly. You may feel that you have all the right answers while your poor misguided friend doesn't see the simple solution right before them. Don't assume that your audience is receptive to your insights.
You run the risk of coming off as self-righteous or just plain old annoying. No one likes a 'smartie pants.' Use this time to focus on yourself. Review old notes from your current job or class.
Do recreational activities, but don't travel to far from home. Brush up on a foreign language. Try to be mindful before you offer your two cents.
