I presented this talk at MetaRefresh 2013 in Bangalore - with the goal to remind us that not getting stuck in the how's of our skill and thinking of the purpose, thinking of our goals is a powerful tool. It keeps us focussed, makes us innovate and makes sure we aren't blindly following other people's experiences.
