Don’t bother about other things; just keep watching whether the wrong attitude is there or not.
When it’s there, keep watching it. When you know it and keep watching it, it’ll get less.
Don’t know it and keep doing something else. It’s not important for the greed to go away, but it’s more important for the mind to experience it again and again and watch it again and again until the mind understands that this is really not helpful.
When the mind finally understands from the repeated observations of its presence and effects, the mind finally gets it that it doesn’t help at all.
It’s a good lesson to learn; you need to give it time. So, watch it.
