That's because the way things are, is nothing, compared to what they could be. And it will always be that way, for two reasons:
1. Adapt. Human beings very quickly adapt to their conditions. As soon as we make progress in a certain area, we get accustomed to it.
2. Growth. As Tony Robbins tells us this is one of the strongest of all Human primal needs. We have a innate longing to improve, change, get better, progress, achieve mastery.
This fact, is not good or bad...it simply is. And it means, we need people to constantly instigate change and make it happen. And there are literally an infinite number of things that need to be changed right now.
