I keep posting this quote because it remains true and has helped me a lot with overcoming my executive dysfunction:
"Anything worth doing is worth doing badly"
It doesn't matter if you don't take all the dishes to the kitchen; just take 1.
It doesn't matter if you don't do all your laundry; just put 1 shirt in the hamper.
If you're in school, turn in unfinished assignments, even a 1 sentence essay.
At work, do the smallest task you can imagine, even if it's just opening a document.
The point is, while all of these things aren't perfect, they are infinitely better than doing NOTHING. Plus, that one small thing will often snowball into doing more. And if it doesn't, so what? You met your goal already. Anything else is extra.
You are not lazy. You are not a failure. There is absolutely nothing wrong with you. It's the world that is wrong. Remember, society has evolved WAY faster than our brains have. Quit placing such high expectations on yourself when none of us are meant to be doing any of this in the first place.
