"What convinces is conviction. Believe in the argument you're advancing. If you don't you're as good as dead. The other person will sense that something isn't there, and no chain of reasoning, no matter how logical or elegant or brilliant, will win your case for you"

This quote by Lyndon B. Johnson highlights the significance of having conviction in the argument you exist. If you do not believe in the argument you are advancing, it will be evident to the other person and no matter how logical or stylish your argument is, it will not achieve success. This quote is a reminder that in order to succeed in presenting an argument, you need to have conviction in what you are stating. It is inadequate to merely present a logical argument, you must likewise be enthusiastic and believe in what you are stating. Conviction is key to persuading others of your argument.
