Life goes much faster now. Cycles are shorter, ppl do not last 30 years in the same company anymore. Humans hate change in general, and change is what happens to our life everyday so if you do not step back every once in a while to take the big picture and decide with perspective (and have the capacity to do so), you just live the present.
I feel like the "speed of life" is an excuse of sorts, where we feel that we are so busy, that we can't take a step back. But it is a catch-22 isn't it? Because we don't take a step back, we end up not having the right tools to deal with the speed of life.
