quit at least one bad habit

Really, I think this is just part of the personality work I’m constantly doing. I work on finding peace in myself, and with that, a lot of things vanish. When I do not feel the need to prove myself to my parents, I won’t sneer unnecessarily at them anymore, for instance.
The worst habit: Letting things out on the innocent.

I want to quit
- picking my lips for dry skin
- scratching the insides of my ears (they itch so!)
- saying “like”
- leaving the house work to everyone else.. but I’m not determined enough.
- saying things just to say something. I often blurt out stuff that I don’t mean this way.
