How can you be positive for 1 day ?

Just curious can someone be positive for 1 day and literally cut the b.s that the brain has been fried from constant doom scrolling. Like is it possible to rewire the brain. I feel like my brain is fried so much because I'm constantly on my phone doom scrolling and using same apps. And whatever I read or watch isn't going in my memory muscle. All that vital information for implementation goes to waste. So I'm thinking like just solely writing a to-do list and focusing on that for the entire day. I want to challenge myself to become discipline for 1 day. I wish they can change my life gradually
