I think of Ben Franklin’s quote above in two ways. The first is how I believe he meant for it to come out, which is being a smooth talker and having a quick wit is great, but you need to be able to actually accomplish what you say for it to mean anything. (Talk is cheap.)
The second part related to this quote is that I don’t think it matters whether you are the one who is physically doing the work or if you delegate it (using your words to convey the purpose/inspiring others to take action to accomplish the goal). That doesn’t matter – it’s about the end result. In that case, saying it well can lead to doing it well (by others).
Do you think Elon Musk is working on a space shuttle, turning a wrench on a Tesla, or doing the bulk of the engineering work to bore a tunnel under Los Angeles? Is Jeff Bezos packaging and delivering each Amazon order? They’re working on their business and focusing on the big picture to move their companies forward. It is still very important to do the other things, or else the companies would go out of business, but without growth, stagnation creeps in and other companies will eventually catch/pass them.
When starting a business, you’ll probably have to do the majority of the work yourself or as part of a small team. That’s probably a good idea because it allows you to have a better understanding of best practices, what not to do, etc. But you will eventually reach capacity (there’s only one of you and so many hours in a day). At that point (or, hopefully, before you reach capacity) you need to think of hiring others to help you. You can then delegate the work that doesn’t need to be done by you anymore. The end result is the same (it gets done), but you get to focus more on the big picture/expanding your business. If you don’t do this, and you are always the one doing the work, the only difference between you and an employee is that you own your job. You’re not a business yet. Because if you get hurt, sick, or want to take a vacation, guess who’s not making money? You.
Have at least a basic understanding of how to do things well, but it is equally important to learn how to say things well, as that is what will eventually free you from the “rat race.”
