How to sell brilliantly
Unplugged
Timothy Leary once said "you're only as young as the last time you changed your mind".
We have three ages. Chronological as dictated by our birth certificate. Not a lot we can do about that one.
Physiological. What our bio-indicators (blood pressure, skin elasticity etc) report. A lot under our control.
Psychological. Ahh...here's the magic. How young we feel.
Leary also once said "women who seek to be equal with men lack ambition". But that's another story.
