If I had to give one piece of advice to a budding entrepreneur, I would say: 'Aim big.'

You need more than just a great idea. Your product or service must add an enormous amount of value to some industry. If the idea isn't completely new, it has to be better, cheaper, or more efficient than what we already have.

The factory model of education is a gargantuan bureaucracy. Some kids are good fits - I wasn't. The system gives you bad grades and tells you you're stupid. You don't think, 'If this kid's not a good fit, it could be the system's fault.'

I found school very boring and frustrating.

Success must never be measured by how much money you have.

When I first came out, I was a film student, and my mom sewed clothes. I was already doing a million things then, whatever it took to survive. If I had to braid someone's hair to get one pound for my lunch money, that's what I did.

Politicians all over the world cater to domestic vote banks. They will spend only on what their constituents want. So unless there is a grass root green movement in a nation the politicians will not be willing to spend money on curbing emissions. More awareness is needed amongst the people to effect the real change in how governments spend.

They pay me way too much money but not enough as far as I'm concerned.
