Answer: The question is not whether to sell or not. You have no choice. It’s the same as breathing. You can’t stop breathing and you can’t stop selling. You’ve been doing both all your life.
The interesting thing is that this may be the first time ever, when you are asking yourself this question. Why? One reason is that you have never been taught that everybody is a salesperson. If you earn salary, work only for food or shelter, draw unemployment or want to dance with a girl (or have a man dance with you) you are selling yourself for something you want, like money, food, experience etc.
Act: Right here, right now start improving your sales skills. Learn how to sell better. Read everything you can find on the subject of selling. Move toward being a remarkable salesperson. And ask the question as often as you can: How To Sell?
