Motivational speech is easy. Look at Obama (swipe ➡). He's one of the greatest talkers. But he has murdered thousands of people. He throws bombs at kids while talking about unity and peace. Someone can give hour long speeches, but I only watch what they do and I feel their energy. If someone's behavioral patterns seem to indicate a vision towards the good, I trust that person. People can fuck up, so look for a pattern. Gemini is known for their talking skills, but also for being good liars. The body never lies though, learn to watch people's body language and micro expressions, watch their eyes. And most importantly, trust your gut feeling around people, always.
