Mars in the 3rd House
  ***************** 
  This infers an aggressive keenness with respect to educational or literary pursuits. 
  You like to gain the attention of others by projecting your views and opinions. 
  Persons with this placement often have a lively mind and a quick wit. However, you 
  may have some difficulty in expressing your feelings. If your intellect and emotions 
  appear to collide, try to be a little more tactful and aim to strike a balance with 
  rational and sensitive forms of expression. With this placement, there is sometimes 
  the danger of overwhelming those around you with your thoughts, although you are 
  capable of inspiring others into activity. In one way your intellect acts like a sharp 
  knife, and it may be very useful if handled correctly, but if you are careless with it, it 
  can be dangerous and destructive for all concerned. Whatever planetary aspects to 
  Mars exist, it's up to you how you use your intellectual capabilities.  
   
  You tend to investigate a number of topics and somehow make them more 
  interesting. You also feel a need to talk about or write down everything that moves 
  you; writing things down helps to release some of your pent up energies. When 
  somebody has annoyed you, it would be advisable to write them an angry letter but 
  do not forget to tear it up before you send it. If you have a tendency for restlessness 
  or suffer from nervous tension, you should try to gain more self-control and perhaps 
  to burn up excess energy through sport. You were probably something of a vigilante 
  in youth, particularly if siblings needed protection. You always seem to be on-the-go 
  and may be perceived as a risk taker.
