Without paperwork
It’s certainly not true in all domains, but sometimes, the paperwork is a luxury. A formality that allows for sorting. A game of who’s-played-the-game and what did they win. A record of a time that has long since passed.
Because you can do a lot of things without permission. A lot of things without formal approval. A lot of things without everyone agreeing that you’re qualified.
You need special training to be a lifeguard; but someone struggling to swim won’t ask for your credentials.
You need a degree to teach art in a high school; but there are no prerequisites for making drawings with your nephew.
You need licensure to practice therapy; but a trusted friend will welcome careful listening and thoughtful advice.
Don’t underestimate yourself just because you might not be fully accredited. There’s much good that you can still do.
