Look, most of us have been there. My first signing was with Notary Go and it was a complete disaster. From printing the docs to missing signatures to missing stamps. I was a complete embarrassment to the NSA industry. There’s no way I would’ve even hired me lol.
Keep your head up, keep pressing on and make Youtube your best friend. There are many many free document videos there. One of which is excellent and very in depth is Coast2Coast. Search them on Youtube and watch their videos. Hang in there, you’ll do great.
