Agency by agency we frequently have lost a bit of ground at least to inflation-but had it not been for the efforts we've made to educate people about the importance of science technology and advanced education those predictions very well might have come true.

So the major obstacle to the development of new supplies is not geology but what happens above ground: international affairs politics investment and technology.

But my view is that you need a system at the border. You need some fencing but you need technology. You need boots on the ground. And then you need to have interior enforcement of our nation's immigration laws inside the country. And that means dealing with the employers who still consistently hire illegal labor.

I love the 3D revolution. I love the technology today that continues to push the envelope continues break the new ground and continues to raise the bar.

My mother was a teacher my father was a community organizer. I come from a working class background.

From a very early age my wife and I told our son that there are times and places for everything. I told him look when you're in class you have to be quiet and listen to your teacher but when you go out to the playground you can scream and be silly.

I have sympathy for young people for their growing pains but I balk when these growing pains are pushed into the foreground when you make these young people the only vehicles of life's wisdom.

I'm in total sympathy with Dick Smith's sentiments I only wish there were grounds for saying we Australians would never tolerate such appalling treatment of refugees being carried out in our name.

Success consists in being successful not in having potential for success. Any wide piece of ground is the potential site of a palace but there's no palace till it's built.

The hardest thing to find in life is balance - especially the more success you have the more you look to the other side of the gate. What do I need to stay grounded in touch in love connected emotionally balanced? Look within yourself.
