Audiobooks are great for when I'm lacking motivation to read.
Also, in today's world, learning how to control my attention is one of the most powerful tools I've picked up. I've done it through mindfulness practices, and boosted it through the use of high CBD:THC pot. If you don't live in a state with legal weed, CBD oil is available online and can be legally shipped.
I can't tell you how nice it was the first time I noticed I was able to sit still for 45 mins without fidgeting.
When I apply my attention to distracting beliefs getting in my way, I recognize I have the choice to believe the thoughts and choose to believe their opposite instead. Choosing to believe a thought isn't a skill many people practice, so most people change their beliefs through the use of affirmations. I do that, as well, and write them on my bathroom mirror with dry erase markers. When I'm brushing my teeth, I read them in my head. When doing anything else in front of the mirror, I read them aloud. If writing your own affirmations, make sure they start with "I," are in present tense, use positive language ("I am ____," as opposed to "I am not _____"), and are emotionally powerful (look for a physical reaction when you say it, like warmth in your chest).
