What moments during the day can you even take five minutes to breathe? Because reading doesn't have to be a full hour session - often it's totally fine to read in bits and pieces.
A lot of people with busy schedules find 10-15 minutes in between tasks: on the commute to work, during lunch, before bed. If you read 15 minutes a day, that's an hour and a half a week - a book will stretch over several weeks, but that's still progress. The key is not to set yourself an impossible goal like "I'll read an hour every day," but pick a realistic format. Some people switch to audiobooks, listen to them while cooking or cleaning - that's multitasking. It's a different experience, but for busy people it's often the perfect solution.
It also helps to schedule a specific time in your calendar - not whenever, but right after dinner with a cup of tea, for example. Or instead of scrolling your phone before bed. It's easier to swap one activity for another than to just squeeze reading into nowhere. And pick books you actually want to read, not just to check them off - if the plot grabs you, you'll find time for it even with a crazy schedule.
