Technology gives us power, but it does not and cannot tell us how to use that power. Thanks to technology, we can instantly communicate across the world, but it still doesn't help us know what to say.
Words are singularly the most powerful force available to humanity. We can choose to use this force constructively with words of encouragement, or destructively using words of despair. Words have energy and power with the ability to help, to heal, to hinder, to hurt, to harm, to humiliate and to humble.
The medical literature tells us that the most effective ways to reduce the risk of heart disease, cancer, stroke, diabetes, Alzheimer's, and many more problems are through healthy diet and exercise. Our bodies have evolved to move, yet we now use the energy in oil instead of muscles to do our work.
The war we are fighting today against terrorism is a multifaceted fight. We have to use every tool in our toolkit to wage this war - diplomacy, finance, intelligence, law enforcement, and of course, military power - and we are developing new tools as we go along.
If we want to address global warming, along with the other environmental problems associated with our continued rush to burn our precious fossil fuels as quickly as possible, we must learn to use our resources more wisely, kick our addiction, and quickly start turning to sources of energy that have fewer negative impacts.
We're all just bags of bones and muscle and hormones; I'll never understand what makes our minds do the things we do. It's like that statue of the monkey holding a skull. We're trying to use a thing we don't understand to understand ourselves.
Economics is all about consumption. People either spend money now or they use financial instruments - like bonds, stocks and savings accounts - so they can spend more later.
Insight into character comes from listening intently to the spoken word. The physical person, their charisma, charm and dramatic flair is more often used to persuade audiences, as they use these stealth tools of disguise and deception.
If it's free, it's advice; if you pay for it, it's counseling; if you can use either one, it's a miracle.
The purpose of terrorism lies not just in the violent act itself. It is in producing terror. It sets out to inflame, to divide, to produce consequences which they then use to justify further terror.
