It's easy to wing it. It doesn't even matter what subject we're discussing; winging it makes it all seem easier. It really doesn't, though.
In the back of your mind you deal with the niggling sense that you might be forgetting something. Did you pack your socks? Turn off the oven?
And that's true of everything you do, from something as simple as packing for a trip to something as complex as building a new business.
For the more basic tasks of our lives, we typically have or make a list. When we go to the grocery store, we take a list of the items we need to buy. When we plan a trip, we have a checklist of what we need to pack... don't forget the swim suit!
But in business, leaders often put off building the list. In many cases, there is a lot of activity and the appearance of forward movement even though there are much more effective ways to do what you are doing. At least you're moving. It seems to be progress.
But, it's not. It's confusing activity with productivity, and it's lethal.
Build your plan first. Make a list. Then (and only then) go to it.
