I just happened to think about that since the start of this year. I would consider evergreen skills that are not industry-specific and are always relevant wherever we go. Two things immediately came to me for me: Sales & Content Creation. You always need to sell, it could be services and product, or it could just be selling an idea. I wrote an article about sales and how to do insight selling. Hope that it would be helpful for you (:
