If you have ADHD it’s not so simple. When I’m off my pills — which is to say every day of my life before I was diagnosed — I don’t really make conscious decisions about such things. I open my computer to work and find myself on Twitter or Facebook or HN or whatever 20min later without thinking about it.

I mean that literally with no hyperbole. ADHD manifests from an under developed or under stimulated prefrontal cortex, which is responsible for such task prioritization and decision making. Without stimulants I’m not really making conscious decisions about most things. Much like how you’ve probably driven your commute sometimes and arrived without really much memory of how you got there (“driving on autopilot”). That’s every moment of every day in the most extreme ADHD case (it’s a spectrum of course and you should seek treatment if you think you’re anywhere on it, even if the above sounds more extreme than you).
