Taking decisions is not easy when all the facts are not known and all the pros and cons have not been understood. This is an unproductive excuse, because, almost all important decisions are characterized by incomplete facts and there is not enough time to sort thru all the options, pros, and cons.
If your mind is not calm and you cannot think clearly, or you are unwilling to try, you will just avoid the discussion and still attempt to move forward. This creates needless confusion and downstream costs.
Start by listing the tough issues in your workplace and post the list in a visible place. This will draw attention to them.
The reality is that you will not be able to tackle the list all at once. You will pick and choose based on a priority or your bias. Nevertheless, acknowledging that a tough issue is unsolved and that you’ll get to it at some point is much better than pretending the issue does not exist.
