define that act of being proactive...?

It's taking advances/precautions of a situation before the situation even happens. The reason behind being proactive (psychologically) is to have more control over a situation, to be better prepared.

Example:

A proactive home owner installs a security system in order to prevent burglars.

A reactive home owner would install a security system after having already experienced a break-in.

You know that acne treatment called Proactiv? Well, that's their whole spiel. Their product will get rid of any current acne and will be proactive in deterring any future acne. Sorry to sound like a salesman for a product, hahaha, but it's something most people can relate to because you've probably seen the product before.
