People make bad decisions every single day of their life. That’s just part of life. I don’t know anyone who doesn’t make bad decisions on a daily basis. Literally bad decisions daily. It doesn’t really mean anything unless those decisions are deliberately harmful to other people. Clearly that friend of yours make bad decisions too as all of us do

Some behaviors could be changed or at least people can try. I am a bad listener. I don’t listen to anything more than few minutes and then I tune out. I can’t do audiobooks or any long lectures or conversations, tune out within few minutes. So it’s just how it is. It’s annoying in relationships with people though because they have to either put it in writing or have to put up with wasting time of their life telling me what happened and me not having a clue what they just said. I am trying to improve. I make efforts or try to find compromise. Deep inside I still am who I am but I am trying to be a bit better.

There is nothing wrong with people trying to be better for the sake of themselves or for the sake of others. We all should try to be better versions of ourselves
