In the Netherlands they claim its 35%, but I believe in reality its much higher.
For myself I found a way to enjoy the work I do. Here is how.
I followed my ambition and started several companies around it. Allowing me to work with diverse groups of people from children from 4 years old tot CEO. One of these companies, The Poetry Jockeys, allows me to work with these diverse age groups on storytelling in which they share their dreams, beliefs and ideas. Having heard and seen so many of these stories I know we are more alike than we often think.
As far as education and career is concerned if we dare to act out-of-the-board, stimulate diversity it could increase our happiness in the work we do.
At least to me it works like this:
Follow your Ambition
Connecting generations through Storytelling
Find a stage like TEDx and share your Passion
So we can forget and avoid these Top 5 "regrets".
