My father died when I was nine, and I remember doing the household chores(杂务)to help my mother. I hated changing the vacuum cleaner(真空吸尘器)bag and picking up things the machine did not suck up.
Twenty years later, in 1978, I was doing chores at home alongside my wife. One day the vacuum cleaner was screaming away, and I had to empty the bag because I could not find a replacement for it. With this lifelong hatred of the way the machine worked. I decided to make a bagless vacuum cleaner.
Easier said than done, of course. I didn't realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes(设计原型). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies. By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem.
I just had a passion for the vacuum cleaner as a product, but I never thought of going into a business with it. In the early 1980s, I started trying to get licensing agreements for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters(滤网).
No one would license my idea, not because it was a bad one, but because it was bad for business.
That gave me the courage to keep going. Then, in 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million, I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain.
Today, I still embrace risk and the potential for failure as part of the process. Nothing beats the excitement of invention. Go out and brainstorm your ideas. You are not bound to any rules—in fact, the stranger and riskier your idea, the better.

Dear Leo,
Know that you are in low spirits for the quarrels with your parents，I would like to help you, but I can totally understand your feelings.
To start with it, you should know what this kind of communication problem worries nearly all the teenagers. Therefore, you don’t have to blame yourself not having a good relationship with your parents.
Actually, it isn't easy for them to talk about myself with my parents either, so my solve is to write down my thoughts in a letter to them. We need to tell them what we want and learn to negotiate. For example, I once get my parents to let me hang out with my friends on weekends unless I got better scores.
What’s more, trust the love of your parents for you and have some faith in them.
They will absolute listen to you and understand you in the end.
I’m looking forward to your good news.
Yours,
Li Hua
