Re: Mercury square Midheaven - problems communicating (especially in public)?
Well Mercury joy's in the 1st house, because it rules the head, intellect and the mentality of an individual. So I think it would help in the education areas. Maybe public speaking would be the sacrafice for the statted above?
I have Mercury in the 1st too, and I am scared to speak publicly. I always get all anxious an nervous. Though I think this may apply to a large crowd, rather than small. Despite the fact that they may not have mercury squaring the MC.
