Quote of the day by Donna Summer : We all have moments when we think we know how something will turn out. A new project looks promising, an idea seems certain to work, or an opportunity appears too small to matter. But life does not always follow those expectations. Sometimes the things we are most confident about fail, while something we hardly notice ends up becoming a success. That is the idea behind a quote from American musician Donna Summer, who reflected on how difficult it can be to predict what will happen.
