focus boost

I really try to stay focus but I lose track all the time with so many distraction's, I was wondering what helped you guys with learning whether its SEO or YouTube. Do you have a certain pattern so you dont over work yourself, I often find myself getting lost in all the information.

I may sound insane but the society around us is moving towards smart drugs and memory supplements. I'm not talking about abusing kinda level. Are there anyone here who's using any kind of nootropics just to boost human productivity?
