if the discourse often gets negative why are you leading the post with "im not going to clown them anymore".
My point is, its not really about being brave to post. Its the constant flame from you with nothing to back it up, and constant downplay when you are apart of projects that dont go well. You seemingly cannot ever be wrong.
You may not agree with everyone (i 100% dont), but the point is they are trying and willing to show that side of their opinion. that is the part thats brave is being okay with the idea you may just be wrong. And if you want to take the next step, thats a concept you need to be okay with.
Instead of tweeting, DO something about it. People are taking strides everyday with similar coaching experience to you.
