I am thirteen years old sitting in front of the first computer that actually made sense to me. My hand gently encloses a beige mouse that's scurrying, with my amateur guidance, leaves a black trail all over the image of a gorgeous geisha brushing her hair. Drawing with a mouse - an everyday action these days, but believe me back then it was a total revelation.
Up until that day when my father bought home an Apple Macintosh's from work the only activity I'd used a computer for was to load games from very wobbly 5'1/2 inch disks and watch my brother write weird languages that made text fly across the screen. Those clunky keyboard-driven machines were totally alien, I instead preferred more lo-fi coloured pencils.
What do you want to be when you grow up?
This is what I call one of life's defining moments - a point on our journey that sparks a passion or idea so powerful it has the possibility of taking our life in an amazing new direction. I have heard stories of this happening in many people's lives, from Ludwig Guttman's quest of help injured soldiers overcome limitations leading to the birth of the Paralympics, through to chef Heston Blumenthal's epiphany while reading the book 'On Food and Cooking'.
These defining moments can be a tiny or ground-shaking. But I believe everyone has at least one in their life. The problem can be that we forget them, or fail to realise that they have happened in the first place. Sometimes it's only by looking back on our lives and remembering those moments when we felt most alive, those ah-ha moments, that we can tap into what drives us as as a person. The thing, or things that makes us really hum.

So, you might like to know - did I actually become a designer? I most certainly did. I got my first design job when I was ten and I never looked back. I am so thankful for where design has taken me, I have loved my career with it's twisted and woven threads.
Loved in the past tense? Why yes, for I'm about to embark on a whole new journey. Another defining moment has led me to a new path which will combine design with another passion of mine; psychology and helping people live fulfilling lives.
Are you intrigued? All will soon be revealed.
Meanwhile I'd love to hear - what has been a defining moment of your life?
