'go ahead, take it upon yourself

… to redo everything all over again?’

people who can’t stay in one state of mind. it’s like they have this sad commotion to be changing all the time, and they are still not content?

how do you help such a person, if you can? share.

They are pain and they are not good decision makers.
Sadly its very hard to change one's nature until they have faith and confident on themselves.
