“One needs to be slow to form convictions, but once formed they must be defended against the heaviest odds.”
Not jumping to conclusions, and not believing everything you hear, is the way to form your own opinions and beliefs. If you are what is considered a ‘gullible’ person, then it will be difficult to truly know what your own convictions are. Search your soul to find out what those opinions are, and hold them dear. When you have them established, you should always defend them, no matter what anyone says. If you don’t stand up for your own beliefs, you won’t seem like a strong person. Stay strong against opposition, and speak your mind; when you have something to speak about.
