There's an interesting quote I hear quite regularly regarding how to act in times of strife or turmoil.
The only way out is through." – Robert Frost
If you think about it, it's a simple allegory for a moment when you may face a challenge, whether work, personal, or otherwise. Given that this is a business-related article, I'll limit my thoughts to the work environment, specifically examples facing business financial executives. The point, however, is that bemoaning the issue, or moment, or whatever the challenge may be, does very little to help you move on from that issue or moment. Action is what helps you more than any other element. Doing something is better than doing nothing almost all the time.
