This is a thought that finds great expression in The Prince and is scattered throughout his work. At first glance it might seem rather obvious, but for Machiavelli it goes to the heart of everything. When you feel necessity biting at your heels, you are moved to respond in some way that is creative. It is either that or die. When you do not feel necessity, your actions lack purpose, your spirit wanders, you grow fat and dependent.
This pressure from the environment does not have to be material poverty. It can be something psychological. You feel unhappy with the world around you and compelled to change something about it or yourself. This dissatisfaction is constant and it focuses your energy.
So now consider these situations..
At work - you feel frustrated by politics and clueless colleagues, and start wishing you worked somewhere else. But what if your next job doesn't challenge you to do better and you get 'fat and dependent'.
The current war - the West is there to fight based on ideals, but for the people who live there it's life or death of their deep held beliefs.
Modern life - with people living in their cosy world of modern, affordable luxuries, there's no pressure to make things better or challenge the status quo.
I think you could apply it to understanding a lot of other things too.
