El método de ventas original de Napoleon Hill que dio origen a uno de los más grandes referentes para el éxito y los negocios a nivel mundial. Con La ciencia de las ventas, un curso dedicado a los alumnos de la Universidad de Extensión LaSalle, en Chicago, en 1913, Napoleon Hill demostró al mundo que no sólo era un talentoso escritor y orador, sino un hombre dedicado en cuerpo y alma a un solo propósito: enseñarles a las personas cómo vender, ya fuera productos, servicios, ideas o, sobre todas las cosas, a sí mismas. Aquí encontrarás las herramientas que necesitas para convertirte en un vendedor exitoso, sin importar la naturaleza de tu negocio. Su método y principios están basados en la experiencia de algunos de los líderes más influyentes de comienzos del siglo pasado, cuya guía te ayudará a negociar sin fricciones, promover tus ideas de forma eficaz, crear estrategias para emprender y cerrar ventas de manera profesional, así como identificar y desarrollar las cualidades que todo vendedor debe tener, entre otras valiosas enseñanzas. ENGLISH DESCRIPTION The world needs new leaders and is rich with opportunities for professional salespeople who are creative, energetic and desire to benefit others. You can be one of them! Many followers of Napoleon Hill often miss the fact that he was not only a gifted writer and speaker, but also a man who made a living teaching other people how to sell. In 1913, Hill began working for the LaSalle Extension University in Chicago, giving him valuable insight into what he liked doing and what he did well: teaching people how to sell ― products, services, and above all, themselves. This book will give you the tools you can use to effectively sell yourself and your ideas. Learn:- The principles of practical psychology used in successful negotiation
- How to create intelligent promotion in order to succeed
- The strategy of professional salesmanship
- The qualities the professional salesperson must develop
- Autosuggestion: the first step in salesmanship
- About the Master Mind
- Concentration
- Initiative and Leadership
- How to qualify the prospective buyer
- How to neutralize the prospective buyer's mind
- The art of closing the sale The ability to influence people without irritating them is the most important trait in salesmanship. This book is devoted to an analysis of the principles of psychology through which anyone may negotiate with others without causing friction. The principles were conceived from the life experiences of some of the most successful leaders in business, industry, finance and education known to the American people in the first half of the 20th century. They are also the principles by which one may win friends and influence people without unnecessarily flattering them.

Best kitchen device!!
Color: Black, Color: Black
This frother is absolutely amazing such power behind it . Quality is just as amazing made very rugged. And I love the stand and the best thing about it is no more batteries to change now we just charge it up. I HIGHLY RECOMMEND this product to everyone and I will be buying more of these for gifts and more for our winter home also. You won’t be disappointed at all.

Works as described
Color: Black
Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.

Very Powerful Frother!!
Color: White
I’ve been using a frother daily for my drinks, and this one really impressed me with its power for such a compact size. It blends heavier powders into smooth, clump-free mixtures in seconds.
I’m a big fan of the build—the metal whisk gives it a solid feel, and it comes with a stand to keep it neat on the counter instead of being shoved in a drawer. Cleaning is a breeze, just a quick rinse, and the rechargeable battery lasts much longer than I anticipated between charges.
Just a little tip: start in a taller cup and don’t fill it all the way to the top, as this thing can create a serious vortex if you’re not careful. Overall, it’s been a super handy little tool, and I’m so glad I bought it.

Mixes my protein shake powder
Color: Blue
My husband and I both drink protein shakes daily. We have vortex mixers that work great, but they are plastic and getting old, and really needed to be replaced.
In an effort to reduce microplastics in our lives, I am trying to use less plastic mixing cups. I couldn't find anything small enough (other than regular blenders) with glass and metal parts that would work well for us.
During my search on here, several frothers showed up. This one caught my eye because of the amount of sales, quick delivery, and of course, decent pricing. Some of the reviews had me a little skeptical, and time will tell regarding the longevity, but so far I am pleased.
My protein powders are on the heavy side, but this little frother really gets the job done. Instead of having to use separate mixing cups (saving me on dishwashing), I just use my morning coffee cup (it's big enough) to mix my protein shake in. My husband just uses a regular glass.
Neither of us can believe the power this little thing has. We are getting smooth shakes!
Here is what I really like about it: It is powerful and mixes well; the frother is metal and not plastic; it cleans extremely easy; after making several shakes the battery has not died; can be used in glasses, coffee cups, even disposable cups (when we buy donut shop coffee); and I love the little stand which takes up barely any counter space. Less plastic, less clean-up, dependable (so far), and small, making it convenient even for travel.
I'm really glad I got this, and hope it will last. One last thing, do not turn it on while cleaning under running water. (Yes, you can laugh.)

Powerful frother with a long rechargeable battery life
Color: Black
After purchasing three of the battery operated frothers. I finally found this amazing frother. It is very powerful so you do have to be careful not to slosh liquid out of your cup when you’re using it. But I have found it helps if you rotate the frother in a stirring motion while you are using it. That really helps keep the liquid from overflowing out of the cup. It has a sleek design and is rechargeable and the charge less about two weeks.I love this one so much. I take it with me when I travel. I actually left my original one at my mother’s house the last time I visited her and have ordered another one for my house. Highly recommend.
