As Mars enters your seventh house of opponents for a long stay, ego-bruising opposition to your actions arises. While failure doesn't have to be the outcome, this influence does threaten complete success, especially once Mars turns retrograde further down the track. Should success come to you, it is likely to be accompanied by loss of integrity. The opinions and actions of others are not likely to support your leadership, and may directly challenge it. Observe the niceties of partnership and restrain your ego, then all should be fine.
