Tricks for when you're the worst at concentrating

This post is about tricks you can use to concentrate better. Something I was seriously the worst at, but I've gotten better at recently. I'm actually writing a book and that requires utmost concentration. Now, I get distracted quite easily, so serious measures had to be taken. And now I'm sharing my serious measures with you.

• Give your phone to your mother, friend, neighbor, someone! It makes no sense to just put that thing away yourself, because you're going to look at it anyway (or am I the only one?). Ask that person to give it back only after six hours (yes, six hours!).
• Install a website blocker, so you can't sneak on Facebook, YouTube, or whatever else. You can install such a blocker here.
• Turn off your email as well.
• Make sure you're alone in a room, people distract you.
• Put music on your head.
• Make a big to-do list and work through it systematically.
• Don't make the room you're working in too warm. Turn the heater down a bit, because warmth makes you drowsy, sluggish, and unfocused.
