What it means
An active challenge may be something you want to take up. A game, an outdoor activity or a demanding task can give your energy a definite subject. You might prefer taking part and making an attempt to remaining on the edge of the activity.
Competition may add another reason to become involved. You might want to test your effort against a target, volunteer for a demanding part or push harder when there is something to contest. Action can be an immediate response rather than the end of a long period of preparation.
An opposing view can receive an equally quick response. You might object abruptly, keep moving with your own approach or resist a suggestion to do things differently. The difficult part can be adjusting an active response when a different idea enters the situation.
