From a tech-enthusiast's perspective, deleting your reading list can be simple. If you're using a browser like Google Chrome, just click on the 'Reading list' icon, usually on the top right corner of your screen. Move your cursor to the article you want to remove, you'll see a three-dot icon. Click on that, and choose 'Remove', voila!
If it's an app like GoodReads, the process is similar. Go to 'My Books', choose your 'To-Read' shelf, find the book you want to remove, click on the 'edit' option and choose 'delete'. Be careful, though, it's irreversible!
