The credit for this idea goes to my colleague Zohar Feldman.
A good way to illustrate the proactive idea is to watch the video clip from the movie NEXT,
In this movie Nicolas Cage acts like a person who can see two minutes into the future, in the clip he is trying different alternatives how to approach a woman he is trying to pursue, understanding why they fail he improves it until success is achieved. This illustrates the proactive idea: event happens, their consequences are predicted and a decision what to do in order to achieve some goal should be taken. There might be different decisions, but we need to predict the consequences of these decisions and make the best one that will get us to the desired solution. Enjoy!
