I would suggest that most dollar problems are cyclical, and when the fed reserve raises interest rates, and the business cycle re-enters an upswing, there will be many reasons to buy dollar.

You achieve your best performance by doing the best you can without having your mind clouded by drifting thoughts of what could happen when something goes wrong. That's what you train for, and your training gives you the ability to build the mental tools and programmes of action to make good decisions.

Criminals are not looking for challenges, but opportunities. Hackers don't cause breaches, they wait for doors to open; and we're making it so easy for people to steal from us that we're creating unlimited doors.

Happiness is a measure that reflects the success with which people achieve their personal objectives of living levels, happy and healthy families and satisfying work.

The strangeness of reality was apparent long before the advent of quantum mechanics. The history of science is a sequence of revelations, each showing that the true nature of things is not what it seems to the casual observer. Quantum mechanics, however, takes this weirdness to a new level.

Gender identity drives self-socialization. People think adults socialise their children, but children socialise themselves. We see the same process in the Great Apes.

We have relatively small groups like Al Qaeda, The Taliban and the Islamic State who are capable of challenging the mightiest and most advanced militaries of the world.

Speed and pace are important – the circumstances that brought people to the table can change over time, nothing is forever, nothing is static.

Are you the guy who wants to know what he gets at the end of the month? Or are you the guy who says I'll take my chances and will do very well or very badly. If you can make that distinction in your own mind, the rest is up to you. That's where entrepreneurship comes from; it means you can live with risk.

Like all primates, we are an intensely social species, and having our friends, cohorts, and acquaintances close is important to our general success. In these senses 'keeping the wheels oiled' is critical, hence why we like gossip, and hence why biographies and fiction so wildly outsell anything else in the books market.

I remember being on a spacewalk and had a few seconds to see a view that humans were not meant to see. It was like I was hearing from God. But then, I had to get back to work.
