My basic philosophy is never do anything with the word 'celebrity' attached to it. Without being overly pompous, if you have worked hard to have an audience trust you a bit, why blow it? That is my currency.

The horticultural industry is unimaginative and dominated by vast, supermarket-like outlets. But the small nurseries and growers remain - praise them with your wallets, not your memories.

A healthy plant is one that adapts best to the situation in which it finds itself. There is no objective measure of this.

My favourite thorn belongs to the rose with a name like a mouthful of broken teeth, Rosa sericea pteracantha. It is grown almost entirely for its astonishing ruby-red shark's fin thorns that are at their lapidary best in early summer, especially when backlit by a low setting sun.

The IMF played crucial roles in the 1980s debt crisis and in the transformation of former communist economies. Radical change, many might argue, is neither necessary nor desirable.

Government has really been growing, a lot of largesse, but the people in the real world aren't. And that's what has to change. Government has no conformity at all with the real world.

Deep-learning will transform every single industry. Healthcare and transportation will be transformed by deep-learning. I want to live in an AI-powered society. When anyone goes to see a doctor, I want AI to help that doctor provide higher quality and lower cost medical service. I want every five-year-old to have a personalised tutor.

Reproductive choice has to be straightened out. There will never be a woman of means without choice anymore. That just seems to me so obvious. The states that changed their abortion laws before Roe are not going to change back. So we have a policy that only affects poor women, and it can never be otherwise.
