3. Leo

Leo people have a lot of confidence in themselves, and this trait can sometimes shut others down by default. According to Berry, the lion glyph of this zodiac sign symbolized a beast so fierce that nothing could penetrate it, including the input of others.

They have strong and big egos and hold steadfast opinions. Even though a Leo will respect other people’s ideas and be willing to listen to them, it will be challenging to convince them to give up their traditional views for new ones.

Leo rules the zodiac, just as the lion rules the jungle. This can make them unlikely to consider new points of view. Since they see them as the most competent and important people in the room, why should they broaden their horizons?
