When an airplane leaves from one city to the next, it has a plan. Its plan is called a flight plan. It's a massive action plan that involves speed, altitude, direction of travel and many other facets. But what happens when there's turbulence or air-traffic congestion or it needs to change course for some other reason? The plane changes its plan. But it doesn't change its goal of where it's going. Create and follow a plan, and don't be afraid to change it if you see something isn't working.
