My siblings, along with my parents Chris and Kath, are the reason that I am successful. Whether I wanted to become an elementary school teacher, enter and win Alternative Miss Ireland, enroll to do a Ph.D., or visit the White House to speak about fashion and disability, they supported me.

People often ask me when I realised that I was different. Some people seem surprised that it's a question that I cannot answer. I was never told that I was different. I was always just Sinead; I was just like my dad.

Using a public bathroom is an incredibly embarrassing experience. I enter the stall but can't reach the lock on the door.

I really never saw an obstacle for me in taking leadership positions because, in a very ridiculous way, I thought, 'If Mary Robinson can do it then why can't I?'

This nation has been drifting back in comparison with the rest of the world for the last 20 years in education.

When I was child, I never spoke. Teacher used to write remarks on my note book. My mom sent me to a trainer. I started talking, and it gave me confidence.

I went to Washington several times at the request of different parties to talk about education reform. I used to always say I felt like I needed to take a shower after I left, because it was so partisan that I just really hated it.

There is so much that is positive, wonderful even, about state schools. At a state school your kids will learn to live alongside and appreciate other kids from many diverse and different cultures.
