    Some of the most powerful companies in the world have co-founders. For example, Google(Sergey Brin and Larry Page),Apple(Steve Wozniak and Steve Jobs),and Microsoft(Bill Gates and Paul Allen)and so on. Having partners can help to deal with the pressure and the failures that come with running a business. No matter how down on your luck you feel they may provide emotional support. They may have extra skills, and be on hand to help out with the day-to-day problems. And an alternate point of view may help to broaden your mind and aid the risk of mistakes being overlooked.

Everybody knows Samsung’s Galaxy Note 7.When the phone was launched in 2016,customers praised it for its storage, design and usability, and it may well have been a hit if it weren’t for the fact that it occasionally caught fire and exploded. It was soon banned immediately from flights, and Samsung had no choice but to recall the entire model. The shortcoming reportedly cost the company $1 billion, and a further $17 billion in lost sales. But remember, based on the lesson, the Galaxy Note 8 and the Galaxy Note 9 are well received in the world! Now we know that failing is part of business success.

One thing that all great companies have in common is that they have failed many times—and luckily, they bounced back. Take Sarah Blakely, founder of shapewear brand Spanx for example. She credits her business success specifically to her failures. “I’d get kicked out of buildings all day long, “she remembered. “People would tear up my business card in my face. But my friends and I knew I could sell and I knew I wanted to sell something I had created. I learned that ‘no’ doesn’t always mean ‘no’ ,and that you may get 30 nos before you get the one yes. People told me no with Spanx for two years. “Spanx is worth just over $1 billion—it was a company that Blakely who took a degree in a law school started with just $5 000!
