5. Do not use the majority
You can’t expect to sound persuasive enough if you use the majority to prove an idea and claim that this is accepted by all people. This is just another myth and a common fallacy that will make you fail. No one will ever trust your arguments if you back up your claims involving the masses. Think of better explanations.
6. Do not use flowery anecdotes
Flowery anecdotes should not be used to replace hard data. If what you say does not sound reasonable and persuasive enough, leave your lame jokes. Otherwise you’ll sound weak and not even funny. People will think you are not a smart person.
