The film taught us how to drill wood to make fire, how to fork fish, how to make bamboo rafts, how to make ropes, and how to use lifeboats. It also taught us: it is best not to wear such unlucky things as "pocket watch + photo".
There are some nice props in the film, like the skate shoes, without which Tom Hanks would obviously have to use rocks. But the biggest suspense is the package that was not opened until the end. I always thought that it would be opened at the last moment and made the protagonist regret it, but it was still not opened.
The film tells us that no matter where we go, we must have a few things on us: a lighter, dry food, and a Swiss Army knife. Otherwise, in this extreme situation, you can only start DIY from the primitive society.
