Bright lights and big dreams are the preserve of the young. Sometimes, as you get older, it is easy to forget what it feels like to have the future laid out before you like a lolly scramble of twinkling stars thrown down from heaven. To believe that you can reach out and grab any dream you like and call it your own is perhaps one of life's most intoxicating drugs.
This week I made my annual pilgrimage to my alma mater to speak to the Year 13 girls about career options.
I used to talk about the ducking and diving and struggling and striving that comes with being a journalist. Thanks to Andrea Vance and the fabulous web of political intrigue currently surrounding her, it's a career that sells itself.
These days, I talk about life as a photographer. I do it because I passionately believe I have the best job in the world and would recommend it to anyone. But I also do it because although the purpose is to help the girls, by default each year it gives my own sometimes struggling life-support machine a bit of a recharge.
There's nothing quite like a mortgage and a stack of responsibilities to take the fun out of any job, and the slow march of time and the often monotonous way it slides by can cause any of us to forget what it was like to push open the door and see the whole wide world waiting on the other side.
