I want to admit that I am an optimist. Any tough problem, I think it can be solved.

Additional Information: This quote is from Microsoft founder and philanthropist Bill Gates' 2009 TED Talk about how we can solve some of the world's biggest problems, such as malaria. The quote means that Gates considers himself an optimistic or "glass half-full" kind of a guy who believes there is a solution to every problem. In his Talk, Gates goes on to say that the reason he has this positive attitude is that he is encouraged by statistics -- for example, average life expectancy is extending, and there has been a significant reduction in childhood death rates because of vaccines.
