We strive for perfection. In order to take one step closer to perfection, everything can be improved. To help you find specific areas for improvement, look in the following places.
Anything that is currently NOT going well. Whatever is not going well, is an obvious target for improvement. There are reasons for a lack of progress. Anything that is not progressing, is being restrained by inherent errors or omissions. Your mission is to identify the errors and omissions that are preventing progress and then, correct them.
Anything that is currently going well. Whatever is going well can still be improved. Failure to improve upon your current performance starts to look like complacency.
Complacency turns winners to losers - no matter how good the current situation is, strive to improve upon it. This is the essence of continuous improvement.
