We talk of less than ideal times to attain the desired solution. When I have this, or at a future date, it will occur.
Inevitably, time or event occurs, and we discover this is again less than ideal. The issue is not necessarily an event or the timing yet how we approach it. If you want to be healthy and fit, why wait until the new year, month or week. If you choose to be less anxious or stressed, the weekend will not give you all you need.
The same for an organization. You have changes you want to make: practices, products, and even people. Later is not necessarily better.
If we are looking to do anything or improve ourselves, there is likely no better time than now.
