For me it was never hard because I started as a kid, on my own, so I was exploring this new world at my own pace and terms, and it was amazing and fun. That's how kids learn. Learning the grown up way is on the other hand harder and takes time. For coding you actually need to master 2 separate, non-trivial skills: first to learn how to think/solve problems in a certain way, and second to learn the particular language. I think the main problem is that people don't give themselves enough time for the first, and concentrate only on the second.
