When we are reactive, we wait until the problem has occurred, and then attempt to solve it. Once we become aware of the problem however, it is oftentimes too late to do anything about it.
When we are proactive, we take steps to avoid the problem. Being proactive for many of us will require a mindset shift. It will be necessary for us to think in novel ways, make changes, and take action.
Being reactive is most certainly easier, but being proactive is the winning choice!
