Imagine you are a quadcopter with a camera.
You take off. For the first few minutes your view is limited, but as you climb higher, you see the whole picture from above.
Now you know where you are and where you want to come, what obstacles are in your way, you see the resources you can use and the tools you need.
All you have to do is plan the actions you need to take on your way from point A to point B.
Write down all the points and follow your roadmap.
