Finding time is never an issue. Every day, you are handed 24 shiny new hours to spend. The real issues (which Aaron addresses) are motivation and mental ability.
You get 24 hours each day, true. But it's not just about motivation and mental ability. The time you have available to read is only time you aren't doing something else. If you have a job, or school, or family duties, or anything else, you may not have much time available to read. Your downtime is available for you to use as you please -- via reading, or watching TV, or whatever. That's when it's an issue of motivation. Sometimes people don't have a lot of downtime.
For many people, time management is really relationship management. I read that on a blog somewhere.
A lot of grown ups, most things we do, we do for other people, in one way or another. So when we pick a thing off of the to do list, we are picking a person to serve.
If your goal is to read a lot, obviously it's primarily a matter of finding time to read. Aaron's advice is extreme, though. Don't isolate yourself entirely -- from people, the world, or even social media like blogs. Each of those has value. As the saying goes, moderation is key.
