Imposter syndrome happens to almost all of us. But remember, if you feel like a fraud, you are not a fraud. A fraud is not worried about whether they are a fraud or not. So just keep learning all you can about your thing, take courses, make experiences, and continue being your wonderful self, and you’ll be just fine. 🙂
Remember that you are always learning. Just because you are a level 2 in something doesn’t mean you can’t teach a level 1. Or just because you are a level 2 at something doesn’t mean you have to stop at level 2, there is always so much more to learn and that’s the fun part!
