Sun/Mars trines always increase a sense of “only I can do this”. You may feel like what you’re planning is in everyone’s best interests and that even if people get upset, they’ll thank you for it later, but Mercury turns retrograde on March 15th. That, along with Venus already traveling backwards in the sign of the Ram, signals that their reaction will be anything but positive. Leo is ruled by the Sun. That means you have to do everything in the light of day. Take the time to win people over and they may support you; go behind their backs and they’ll certainly condemn you.
