Whenever I see a client with Mercury (communication) in Leo, I know it's essential that their words are appreciated. Doesn't matter what they do for a living; the way they express their thoughts is going to have a touch of drama. And they'll want an audience.
Mercury moves into Leo from August 8th to August 23rd. This is a quick transit, but here's the theme; words that are appreciated. Think of the actor on stage, captivating the audience with his lines. This energy is excellent for boosting awareness of how you express your special purpose/goal/needs. It's also supportive of bold proclamations. When you talk, do others listen? Do you waste precious words on an unappreciative audience?
From August 8th to August 11th, Mercury in Leo will be crunched by a square to Saturn (limits) in Scorpio. These few days may present reasons why your ideas are not good enough. You could make an announcement, only to have it shot down. But it's only three days. And the silver lining of a Saturn square is that it forces you to take responsibility for what you say, and work a bit harder to convince others that you're golden. If your ideas are worth it, so is the effort you'll put into them.
If you have planets in Leo, Scorpio, Taurus or Aquarius, you'll feel this Mercury transit most strongly.
