Waiting for you ship to come in means depending on the captain of your vessel finding the right harbor and that isn’t always a given. There are a lot of bad captains out there. Why wait for your ship when you can be doing the sailing and navigating yourself? Why wait for someone else to provide you with what you’re looking for? Ships sink, capsize in rough weather, and you never know when there will be a dockworkers strike. No one ever crossed the ocean just standing on the shore. There is a lot more to getting something done then just wishing that it did.
