Stop fearing failure
This is one of the most important things you need to keep in mind if you are aspiring to become a billionaire. It is completely normal — and in most cases virtually inevitable — to fail from time to time while working toward an ambitious goal.
To give you an example, James Dyson, the man who invented the iconic Dyson vacuum cleaner, developed more than 5,000 prototypes before coming up with a product that he thought was good enough to be sold to people.
The rest is history. Do not lose hope or give into despair when you fail. Instead, look at it as an opportunity to learn a valuable lesson and move on to the next big thing.
