There are times when groups may not be as useful as others. It is important to know about that as well. So let’s look at some of these circumstances.
When you have limited time, it may not be a good idea to use a group. As you have already discovered when your plans involve you and several others there is always a problem of coordination and time. When you are worried about a decision and it must be made quickly you’re pretty much stuck with you and if you’re lucky someone you are with who is informed. That isn’t the same as quick decisions are better. Often they are not better. Keep in mind that there are many situations that call for a decision made quickly to avoid disaster. Later, upon reflection you may think of several other possibilities than the one you chose. Put another way, whenever possible anticipate and plan ahead. Avoid backing into situations that call for quick decisions.
