The most successful teams are the ones who present with authenticity and passion. You could have the next cancer cure, but unless your audience believes in you, they won't invest in you.

Women were never in the driver's seat with dating. It always came down to the man to take the lead, to ask the girl... There was this playbook where the guy has the power, the girl is weak and fragile waiting to be saved by Prince Charming... and this is disempowering for both sides.

Germany for example, has decided to close-down its nuclear industry. That creates a huge electricity deficit, and there is the potential to produce a large amount of renewable energy in Greece and export it to countries like that.

In the short-run, my fear would be that we've mismanaged the relationship with China through miscalculation to produce a 1914-like situation. There's obviously the danger of nuclear weapons and a miscalculation leading to their use, and inevitably therefore, catastrophic outcomes.

We have a much more connected marketplace. We have had, what I reckon to be an extremely overvalued stock market since 2000. When you have that situation, you are prone to very sudden negative revaluations.

This concept, while vital to have in mind in considering the lawfulness or otherwise of use of force in almost all armed conflicts, lacks a precise definition.

There is a significant part of the Greek economy- maybe 30-40%- is not in the 'official' books. That has to be reined in. To put this in context, if that is reined in… to a large extent, the revenue side of the Greek problem would be fixed.
