Deal with the unexpected. Learning to deal with the unexpected sounds like an oxymoron. If we can predict something and prepare for it, it's not unexpected. Yet every unexpected event, however unique it might be, produces specific neurobiological pressures in us which we then must work hard to overcome in order to make better decisions and take actions that benefit us.
As it turns out there are small things we can implement in our daily lives that can better prepare us for adversity by hardening our mental and emotional responses.
