It's always about people
I have had the privilege to be a part of some incredible projects during my career. Doing great work requires great judgement and intuition, both of which come from wide-ranging experiences and tasting both success and failure in some measure.
Whether it was making sure thousands of workers got their fair dues or creating a software used by one of the biggest professional service firms in the world, it was always about the quality of work and the quality of individuals I worked with.
There is nothing more important than the quality of people you work with. Success, whether individual or collective, has always been a group initiative. A small team of A players can work magic that larger teams of B and C players cannot even imagine.
