I think the best way to apply what you learn is to make sure you're always learning. I'm a big believer in lifelong learning, and I've found that it's not just a fun way to spend my time—it's an incredibly effective way to take what I'm learning and bring it into the real world.
I think the most effective way to do this is by making sure that every day, you're reading about something new and different. Don't just read about your favourite subject: read about something new! You can do this by following people who are experts in different fields on Twitter or Facebook, or by subscribing to their newsletters. When they post something new, it will show up on your feed and give you an opportunity to learn something new.
