How do you deal with procrastination/laziness?

The kind where you know you have to do stuff, but avoid getting around due to distractions/difficulty/fear etc?

Executive dysfunction you mean? ADHD meds can sometimes help, also having external authority forcing you to do it

I also sometimes cope by impulsively doing it if I have internal motivation, but that can lead to doing unwise things too

Not sure.
Was recommended a ADHD online test in another post on this similar topic. It said that I likely did not have it.
