Learn to fact check and learn how to research on a certain topic that you can use for cross referencing to provide an accurate if not the best answer regardless of the nature of the topic. This means that you really know and have applied what you are talking about and not just some random gibberish content just to achieve certain quota. You are only entitled to give an opinion or advice as long as you can defend it morally and ethically.
And if there are members who corrected you in the middle of the discourse, then it would be best to absorb what they teach you like a sponge and never repeat the same advice you have given before.
