A toxic person kills, and by kills I mean totally destroys teamwork.
Your work speaks for you.
You have no idea if your idea matters until you share it.

Watch with awe and amazement at how quickly an engineer will become totally annoyed by inefficiency.
Start with something messy, get to the point, get an editor, and make it good.
