A good machinist knows there's a lot more to making a part than hitting cycle start. There's planning. Programming. Material prep. Tooling. Workholding. Setup. Proving the part out. First-article inspection. Only then do you get the green light to run.
Anyone outside the trades usually doesn't see this, but the people in it live by it every day. There's always more going on beneath the surface.
What's interesting is how few of those same machinists apply that same thinking to their own lives.
