When things are going well, it's easy to maintain focus; because it's pleasant to keep an eye on the parts of your life or business that are going smoothly. But when plans go awry and people around you begin looking for answers, your focus can be split across multiple problems, or even the perception of problems.
On the footy field, just as in the office, when things are going well, we tend to become complacent and allow positivity and optimism to rule our behaviours. This is good of course, but sometimes it blinds us to problems in our strategy that may arise later, and as a result, we end up coming undone, perhaps in a way that could have been avoided if we had maintained our awareness.
A team playing well, but with a heavy reliance on the skill of a single player, can be looked at as both a great situation - we've got a great player - and a problem to be solved - what happens if that player gets injured? The same is true of an office sales team or a business unit that relies on the knowledge or skillset of a person. If they leave, what happens to that knowledge?
Far too many businesses and sports teams have been shell-shocked by the departure of an individual whom they had an unhealthy reliance on, and paid the price for poor planning, and a lack of action.
