We often spend a great deal of time and energy in our lives building spaceships. Well, not real ones, but in our heads. We take something simple, and we add, and add, and add until it is very complex.
Each layer of complexity that we build is another layer to stop us from starting something.
Simple things are easy to start so we make them complex, needing perfection before we can do.
Perfection is the shield to stop us starting.
Keep things simple and start.
