Is it me repeating the same things or is it companies that promise us to change do the same mistakes again and again?

Thanks

Is it about wrong or right? or is it about having an argument and just throwing opinions as statements without any explanation. After all — all of us can be wrong, but we can have opinion and we can see results. I could use "told you so" so many times here, but still people would not listen to me, but for some reasons if you have a lot of thanks and better in writing you can just throw few sentences and people would build you a statue Is it about self confidence?
