Pick your battles. It isn’t necessary to have an opinion about everything. Select only those topics which resonate most with your beliefs, morals, and values or affect you personally.

Get the facts. The facts both inform you and add validity to your stance.

Learn what others think. Listen to discussions, debates, or even arguments. Keep your mind open to all ideas.

Skipping either of the previous steps will generally cause you to look stupid.

Judge for yourself. Determine whether or not what you’ve learned is both reasonable and logical.  Weigh the pros and cons based on your own ideas and feelings. Then, after some consideration, form your own opinion.

Be aware that others may not agree with you. Don’t take this personally. Differing opinions happen. Your opinion is based on how the facts and your knowledge of the subject work for you. Acknowledge that others have formed their opinion in the same way.
