I need to stop procrastinating

Like I have quite a bit of stuff on my to do list that I really should get done and I wanna get it done but like I'd rather just stay in my room and do other things like watch YouTube or browse Twitter or talk to friends on Discord or make a blog on SpaceHey about how I'd rather watch YouTube or browse Twitter or talk to friends on Discord instead of getting things done that I need to do. It's like I think in my head that it'll take super long to do and then I do it and I get it done quicker than I thought so I know it doesn't take that much time but I still avoid doing it because I think it'll take super long to do. It's a bad habit of mine.
