As a reader, what I do is make up my own challenges. Do I feel comfortable modifying the code and knowing it will still run error-free?

I do the same when learning a new concept, find a little way to apply it by slightly to heavy modifying the original code until it clicks. I save those to a folder I can reference sometime in the future. I’ve been doing this for a really long time and it works well for me.
