I'm fascinated by Eric's suggestion that personal growth may be considered the beginning of a futuristic revolution. I also agree with Mark that we don't necessarily notice changes going on right around us, even if we're involved.
The industrial revolution certainly transformed the world because it helped human beings expand their views of limits and potential. That historic era taught people that complex and radical socio-economic changes could have a domino effect in ways that could enable them to enhance other areas of life. These changes were varied and based on initiatives outside themselves.
If we turn to the impact of personal growth and self-help initiatives, this modern industry develops offshoots in alternative medicine, spirituality and other areas which enable people to expand on what they think they know and change from inside. Personal growth reveals we have potential to transform how we see and learn about ourselves and the world. People may forget that a sudden change is actually a synonym for 'revolution.'
