When I'm trying to change behaviors I set very specific goals.

If you want to read more, but reading fan fiction is your obstacle, here are a few approaches to consider:

Put a time limit on your reading of fan fiction, or a limit on how many outlets you browse. Turn off notifications and email alerts/newsletters.

Another approach is to reward yourself with fan fiction for reading books.

Read books on the same device you would normally read fan fiction, you can borrow ebooks from the library or purchase them online, so you can read on your phone, tablet, or computer.

Set a goal of how many books you want to read per year, then break it down by month, then by week. Set time aside to read. I find it easier to pair a habit with another activity. Maybe read on your lunch break, or read before bed. Consistency will increase your chances of success.

Celebrate or reward yourself for reaching your goal, any goal, it can be a weekly goal or each book you read.

Many people find having accountability increases the chances of them reaching a goal, so make your goal public, or share with a friend, then check in often with your progress.
