Revolution is an external change where Evolution is internal.
When a revolution occurs you change your job, cloths, living arrangement, geographic location, etc Your "External Stuff".
When Evolution occurs this is when you have become someone more, else, better, different! Yoh have graduated college is an example of Both, however most of the time you have learned and changed internally so your view of your world is very different even though you have not changed externally in any way. But internally ... WOW it is as if you just attended aTony Robbins UPW!! You have definitely EVOLVED inside like a bomb went off.
If you do not know who Tony Robbins is then you must check the rock star of a solution master out. He will change your life.
