The loudest person in the room is the weakest person in the room.
Notice the heads of families, heads of companies and leaders of private organizations are always quite than those lower than them. They listen 10X more than they talk. They handle each situation with the wisdom of years of experience and dealing with people. They understand those that talk a lot, often do not strategize what they are going to say. Which can lead to saying something offensive, out of place and ignorant. Powerful people think before they speak. They plan out meetings and negotiations before they take place. They are 5 steps ahead. They already know the other person is the sucker at the deal table. Shut your mouth and be receptive to EVERYTHING! Learn from others, read books and find mentors with the same interest as you. Become respected by speaking less and speaking with power.
