Children Used to Get Bullied at School. Now They Go Home, and That’s Where the Problem Starts – Because They Sit on Their Phones All Night, Thinking About Who’s ‘Liked’ a Photo of Them, Who Hates Them, Who Loves Them. They Don’t Know What’s Real and What’s Not, Editing Their Lives Constantly to Fit Other People’s Views.

I Remember While I Was at School Some of My Muslim Friends Talked About a Handful of People Spoiling Things in Every Culture. Hatred or Hurt or Pain Isn’t Specific to a Religion. I Think It’s a Matter of Acceptance. the One Thing the World Has to Accept Is Everybody Is Different. What Is Normal to Us Is Different and Unusual to Somebody Else.
I Think Being Nice and Being Safe Is Unfair to Yourself When You Have Big Dreams as a Woman. I Think You Have to Prepare Yourself That Not Everyone in This World Has the Same Personality… the One Thing I’ve Chosen to Be Great at in My Life Is Singing – so Why Not Be Proud That I’m Great at It?

You Should Never, Ever Apologize for Anything That Makes You Happy.

This Is Who I Am. Let’s Enjoy It. Let’s Just Live Life to the Full While We’re All Here.
I Had Knockback After Knockback Before I Got Anywhere. After I Got My First Record Deal I Thought That Was It, Then Gut Records Went into Liquidation. I Was 20. I Had No Idea What That Meant. I Had a Few Days to Get Myself Out of That Contract or My Work Would Be Owned by Someone Else.
During My Stage Shows, I Am so Energetic. It’s Constant! I Just Don’t Stand Still. I Actually Got Given a Mic Stand from My Team to Say ‘Just Calm Down. Stand Still for at Least Two Songs.’ but Now I Just Pick It up and Walk Around with It.
I Always Imagine the World and Myself Above It and How Minute One Negative Person’s Voice Is in Comparison to the Amount of People That Are in the World.
I’m so Happy People Are Seeing the Eclectic Side of Me. I’m Really Honored to Be Able to Push My Voice into Different Sounds. Otherwise It All Gets a Bit Samey Same.
Look After Yourself; Remember That You Only Consist of Your Being, so Make the Best of What You Have and Look After It. Put Good Things into Your Body; Eat Well.
It’s Weird Because When You Initially Write a Song, You Write It with No Understanding That the World Is Maybe Going to Hear It One Day. so When You Go into the Studio, You Don’t See the Hundreds of People at a Gig or the Viewers on TV, You Just Write a Song Without Any Inhibitions or Boundaries.
