In Working Identity, Herminia Ibarra argues that people make big changes by taking small steps and noticing the results. She writes about people who have made significant changes in their career paths - and the message she takes from the people she profiles is this. Change doesn't happen because we think about it. Change happens because we do something.
We learn who we are by what we do. A little bit at a time.
Think about the day ahead of you. Assume "I am what I do today."
What one small step will you take in a new direction now?
