If you have an entrepreneurial take on the way you live your life, it is likely that you're already familiar with the importance of being able to convey an idea or to present yourself in a way that motivates others to work with you.
In light of my recent experiences in the the post-graduation world, I think that knowing how to sell or knowing the process of making a sale is an invaluable skill to have. A sale is inherently more complex than someone deciding to make a transaction. A sale involves researching to find and target prospective buyers, developing knowledge and understanding of what it is you are selling, and then articulating this knowledge in a persuasive manner so that the buyer decides that your product or service is a worthy or functional purchase.
Believe it or not, transactions like this happen all the time in areas that you wouldn't necessarily think of as the world of commerce. Ideally, the ability to sell is quite helpful in what could be referred to as human commerce. An excellent example occurs in the process of job searching. Effectively, when searching for a job, you're selling yourself to potential employers. If done correctly, you will have taken the time to sit down and decide what skills you actually possess, to research and find companies that are in need of those skills, and once you're knowledgeable of your skills be able to tell these companies that you are in fact capable of fulfilling their need. This then is an example of why it is vital to know how to sell and is where it becomes a skill that can translate to many facets of life. Many would argue that a little sales knowledge could have saved many failed start ups. Its important to realize that many everyday interactions can benefit from sales experience. Getting a loan from a bank, convincing your extended family where to take this years family vacation, and pitching your business plan are all examples of "sales" you might make.
I may be taking a bit of an extreme position here in the interest of playing devil's advocate but I do believe that the ability to sell can serve you many times over and is essential life skill for anyone, no matter their business or occupation. How important do you think it is to know how to sell? Am I using the correct terms when applying it to real life situations? What experience have you had with this philosophy? Has it helped you?
