Supporting focus

Hello guys! Do you know how to support focus? I'm really bad at time management, and I do everything at the last minute because I can't concentrate enough

I think you can watch some time management videos on youtube or something like that. Maybe they'll help, but I'm not sure

What's the point of knowing the theory when you can't use it in practice? I know a lot about time management, but I can't make myself focus on one task. Well, since I started taking these gummies www.neurogan.com/cbd-products/snacks/cbg-gummies/ , the situation has improved, but it's still pretty hard for me to do something for a long time without any breaks.
