Don’t ask yourself what the world needs, ask yourself what makes you come alive. And then go do that.
I had been practising law for 25 years when my brother suddenly died. I took some time out and never went back. Eventually I decided to train as a psychotherapist - something I had actually wanted to do ever since I was in my teens. I trained at the CCPE, and I am now registered with the BACP. Now, at last, I feel in the right place doing the right thing.
