Newton’s third law of physics states “For every action, there is an equal and opposite reaction.” It’s true of the creative process too.
I’ve noticed a tension present in most creative work. The ideas and projects which are the most exciting and motivating also have the most inertia.
The cause of that drag can be laziness, distractions and self-doubt.
That tension doesn’t feel pleasant, but it’s a telltale sign that a project is a good idea.
