What I'm about to say is nothing new - I've discussed working under constraints many times in the past. But, after my post on the deleterious effects of working at full utilization, I had a moment of insight that allowed me to coalesce some feelings into more meaningful thoughts. I realized that part of what makes me (and my team) so effective is that we "embrace the angel of death". Because the very existence of our team is in constant jeopardy, we have to assume that we won't have time to finish our work; and, we plan our feature development accordingly.
The final way to attain personal freedom is to prepare ourselves for the initiation of the dead, to take death itself as our teacher. What the angel of death can teach us is how to be truly alive. We become aware that we can die at any moment; we have just the present to be alive. The truth is that we don't know if we are going to die tomorrow.
When we accept the fact that we can die at any moment, it allows us to live in the present; and, to make choices that we know we will be happy with. It's the bromide, "Live every day as if it were your last"; only, it sounds much classier as Toltec wisdom.
