All those comments really bother you don't they?
Why not just go in and fucking kill it for the foreseeable future and let the haters fuel your fire?
Some people need a dose of reality, I see it everyday. Whether it be at work, at home or in the gym. Being honest is often harsh. But it isn't a put down, it is an honest observation.
Now I'm not saying this particular case isn't a put down, I don't really care, but not every observation or mention of constructive criticism is a put down. Irrelevant of how "hurtful" a comment may be, sometimes they need to be said, or the individual in question will never change and just keep placating themselves.
