Getting something done to a sub-par level but with a reasonable amount of effort and time is better than doing something perfectly with an immense amount of effort and time spent.

Sometimes we just need to do the thing, and not worry so much how well we are doing it. Most things, we will be terrible and slow at until we do it repetitively to learn more efficient methods.

Sweeping and picking up the house used to be terrible for me, now its mindless and somewhat relaxing. Ive done it so many times it takes zero mental effort anymore.

Be patient and forgiving with yourself, and manage your expectations if you can. We can be incredibly hard on ourselves.

Edit: also be careful comparing yourself to others! Especially with people in this post mentioning ADHD, you will find people who are taking stimulants to push their productivity, which I personally think is short-sighted and unhealthy.
