I know it’s daunting and a little intimidating, but there are so many people with knowledge to share. I see them answering questions, sharing knowledge, and being helpful to the community, so when are you ready to start speaking?
The answer probably varies, but what I’ve seen in many areas is that when you think you’re not learning much from hearing other people speak, you are ready to give your own presentation.
There are other things you need to learn, how to present effectively, communicate, not die of stage fright, etc., and those are skills to develop, but the hard one, the knowledge, is something many of you already have.
Most people want to be an expert in a topic, but the reality is that you don’t need to be. You just need to be organized, brave enough to stand up, and willing to try.
