Often, we get the fear of not wanting to put something out to the public without perfecting it first and being truly proud of what we sent out.
However, this fear often takes the driver's seat and causes no content to be put out. This is an interesting phenomenon, where we know we aren't good at something without practice and yet won't share something we aren't good at.
In reality, no one cares one way or another about your content until you're good. This is somewhat comforting as no one will think less of you for sharing it as you don't have interesting enough content to keep someone's attention. But even if they criticize it, you can take comfort knowing that they thought your ideas were important enough to review and spend time crafting a response. So either way, it's a win-win.
So I think, as a teen, this is the perfect opportunity to get all the bad stuff out of the way while we're young, then as we mature and develop, we come out much farther ahead than those who decided to wait before sharing their imperfect content. There is so such thing as perfect out of the gate, so why pretend to be perfect. Go into it knowing that you're going to do a bad job and that the next time around it will be better.
One quote sums this all up is:
"You can't perfect what doesn't exist."
