Only those with skin as thick as elephant hide can hope to sail through their teens unscathed by self-doubt and bouts of depression.

The point of the feminist movement wasn't simply to set our underwear on fire and muscle into small spaces in the male-dominated workplace, but to create a world where the contribution of both sexes was equally valued and no one's worth was judged on their take-home salary.

Joy acts like a trampoline, everything that touches it bouncing right back off it.

Life is rife with frustrations, jealousies and, on occasion, an overwhelming sense of its injustices, but it's a big mistake to let such negative sentiments rule our lives and dictate choices.

Sustaining true friendship is a lot more challenging than we give it credit for.

Every friendship goes through ups and downs. Dysfunctional patterns set in; external situations cause internal friction; you grow apart and then bounce back together.

We invest less in our friendships and expect more of friends than any other relationship. We spend days working out where to book for a romantic dinner, weeks wondering how to celebrate a partner or parent's birthday, and seconds forgetting a friend's important anniversary.
