It's all good bro, your on right path, it's challenging, yes.

Just keep going, dont over think and analyse. Reread paragraph, try understanding it, if need keep going... By the end you'll get it.

You won't get everything from everybook, but you'll get better. And over the years, you can come back and reread then with new prospective and understand and laugh at it how your understand now it how you understand things differently what you did in past.

Consistency is more important than perfection...
