If one is not prepared to fail, there is no way to achieve success in business and life.

I've tried to solve problems to the best of my knowledge. Many times I was successful, but sometimes I also failed. And now I finally understand – that's life.

Success and failure are relative categories. Therefore, do not exult in victory and do not despair after defeat. Accept the changes in life placidly, knowing that autumn and winter come after summer.

Spreading knowledge is the most effective weapon for defeating ignorance.

Life is the greatest teacher because it educates even those who really hate to learn.
