This is more of a mind decluttering topic than housekeeping, but I wanted to post here because this is such a pleasant and constructive board and I think it sort of fits in here.
The other day I read a column by Lucy Mangan in which she listed a number of things she needs to actively avoid doing, i.e. a To-Don't List. Stuff that is self-sabotaging and stupid, things where if you don't do them you will feel better and have more time for stuff you do want to do. The one that really struck a chord with me and made me want to write my own list was 'Staying up until 1am for no reason'.
I am a bit of Queen of Self-Sabotage. Here is my list so far:
Staying up until 12.30 or 1:00am. This is a big one. I feel blitzed by tiredness all the time and I know it is bad for my brain 
Visiting AIBU or Brexit boards.
Reading online news generally.
Feeling guilty or envious about activities I don't have time to do.
Reading interviews or Q&As with actors.
Getting annoyed with my cat.
Spending more time at work than I do asleep.
Procrastinating instead of doing cleaning jobs which I loathe and then feeling really fucked-off about the state of the house.
Please share your lists with me!
