Having a hard time going through with creating a YouTube channel

I've been wanting to create a Let's Play YouTube channel for a while...probably somewhere around 7 years (I'm 26). Every time I get close to going through with it, I find a reason not to. My hesitation mainly stems from a fear of things like doxxing and the feeling I wouldn't really be adding anything to the sphere. I'm also a college student so time is not in excess. Despite all this, I still come back to the idea.

For those of you who have a YouTube channel or twitch stream, how has you experience been? I know to expect certain things (trolls), but was there anything else that came as a surprise to you?

For my fellow hesitators; what stops you from creating videos or streaming? Do you think you'll ever truly be "ready" to start?
