The best thing to do is not to flick through random short videos. It is best to read books and browse products in online shops. Just look at things and read interesting things.
I was looking at all those Chinese online shops like Temo to see if they sold cheap electric bikes, it turns out they do and you can get the price down to a few hundred £s. I have no intention of buying an electric bike, I just thought it is amazing that fully electric bike with self power mode can be bought for such a low price. Then I was looking at recliners like the lazy boy and train sets. They are low priority things but I was looking at them anyway so I could stop thinking. The key is to stop thinking when it is time to rest.
When you're done looking at interesting things, the next thing is to read books. If you have an Amazon prime account, you can read through some books for free. There is also a library e-book site called Libby that lets you borrow e-books from your local library. If you don't want to read books, you could read this blog, there are thousands of entries spread out over many years. I have a New King James Bible, it has a satin ribbon bookmark built into it so I can save the location I am at. It is nice to read the books of the prophets and see what they say will happen in the future. Then there is the gospels and then the letters to the early churches.
