Quote of the day by Arthur Conan Doyle : Love can be complicated. We may care deeply about someone, lose feelings we once had or find ourselves experiencing emotions we never expected. The difficult part is that feelings cannot always be switched on or off simply because we want them to be. But while we may not have complete control over what we feel, we do have more control over what we do. That is the idea behind a quote by British writer Arthur Conan Doyle, best known for creating Sherlock Holmes.
