An encouraging admission
Perhaps the most reassuring thing I have ever heard while studying Spanish was hearing Andrés admit he was not sure whether ¨sueldan" or "soldan" was correct.

The second most reassuring was being told by a Colombian who reviewed a short story that theoretically was appropriate for intermediate level students of Spanish, but which I found almost impossible to understand that it was rather very advanced, in an antiquated and highly literary style that many native speakers would find challenging.
In short, I think many students are like me, beating ourselves up over our failings when sometimes our material would challenge native speakers and we need to cut ourselves some slack.
