It means to be able to break down a big system into its sections and putting it back together. The target is to identify the strong and weak links: how the sections work, don’t work, or could potentially work and applying this knowledge to engineer useful outcomes.

There is no engineering method, so modular systems thinking varies with contexts.

• The ability to see a structure where there’s nothing apparent.
• Adeptness at designing under constraints.
• The capacity to hold alternative ideas in your head and make considered judgments.

We get to see further than our predecessors, not because we have a greater vision or greater height, but because we are lifted on their gigantic stature.

There are giants in every field. Don't let them intimidate you. Take from anywhere that resonates with you and inspires or fuels your imagination. Build upon it and improve it. Doing this will make your work authentic. Authenticity is invaluable; originality is non-existent.

We increasingly find it difficult to focus on the hear and now without checking our phones. We seem to go through life in a state of "continual partial attention." We're there but not aware of where we put our attention.

While modern technology has its advantages, our attention span is suffering. Teachers are noticing that current students find it hard to read books that previous students used to enjoy. Teachers think that students' ability to read has been compromised by short text messages and video games.

• Sensory: We can more easily tune out from sensory distractions. For example, the feel of your tongue against your upper palate is an incoming stimuli your brain weeds out.
• Emotional distraction is more difficult to tune out. When you overhear someone mention your name, it's almost impossible to ignore.

Those who focus best are relatively immune to emotional disturbance.
