How important is what you are grappling with now? If it’s very important in terms of results it can create for you, and the consequences of not achieving desired outcome are big, then it requires your undivided attention.
Get all the facts on the table to expedite the decision-making and planning process. When you have incomplete information, it takes much longer to decide and plan. If you desire efficiency, avoid discussing outcomes before you have all the facts. If you are meeting to discuss the facts you need, that is fine as long as you are clear of the meeting’s purpose.
Thoroughly preparing for a meeting can greatly enhance the outcome in terms of the overall results.
