I tend to be "that guy" who actually enjoys giving his attention and advice for free to people everywhere, be either offline or online. And when I try to help a bro who openly admits that he's trying to do something and I have a better suggestion to make, I just can't hold myself back from saying it. What's worse, once I share anything they will most likely ignore me and I'll feel weird/offended.

Why I'm asking here? Because I have the suspicion that this is a relic from my "mr. nice guy" years which always finds its way in my behavior. How do I shake it off?
