Building a successful company (or living a happy life, for that matter) is not about embracing someone else's philosophy, but staying true to your own beliefs about the world and learning from the mistakes you make along the way.

Point-to-point transit via low orbit could dramatically speed up international flights, connecting the world even further. And safe, consistent space travel opens up the possibility of commercial space stations, trips to the moon and exploration beyond.

The big reason why we don't have space colonies and regular trips to the moon is that flying into outer space is just plain 'hard.' The business of safely transporting people off the Earth is a costly affair that requires a lot of technology.

Entrepreneurs may be brutally honest, but fostering relationships with partners and building enduring communities requires empathy, self-sacrifice and a willingness to help others without expecting anything in return.

With the amount of planned and unplanned travel I have, it is critical for me to treat my curls right on a daily basis.

There are people all over Australia who use their homes as hubs that they travel from, and they encourage their indigenous people to continue to stay there.

I have likened writing a novel to going on a journey, with some notion of the destination I will arrive at, but not the whole picture - which emerges gradually as a series of revelations, as the journey goes along.

Every day is intense and alive, whether it's travel, work, even down time, which there is so little of.
