"Great minds think alike." Or so they say. I hate these expressions. Clichés, idioms, old sayings, etc. All these do is limit how people see the world, trusting an all encompassing phrase. I find it especially frustrating, when I couldn't disagree more with them. So while you say, "great minds think alike", all you are doing is to justify that you have a similar opinion as somebody else. You know what makes great minds "great"? They see the world differently. The ingenuity and innovation they provide to push humanity further and further. Great minds think differently from everyone, that's what makes them great.
