There is a famous saying going like this，“Our destiny offers not the cup of despair．but the glass of opportunity．” What call we learn from it is that the world is filled with so many opportunities and we can make the most of them by being enthusiastic．
    “Nothing great was ever achieved without enthusiasm，”wrote Ralph Waldo Emerson，which means that unless we are enthusiastic and passionate about what we are doing，we are less likely to see it through to the end-achieving it．Enthusiasm keeps us young and energizes our days， even when there are obstacles and distractions working against us. Without enthusiasm．however，there is no“drive”behind what we’re doing and we just don't have the energy to keep things fresh and to keep learning. If we lack passion in Our endeavors，how should we ever be creative enough to have something to be considered great?
    In a word，life is worth living with enthusiasm and it is the most important thing for each individual：that’s why we should be enthusiastic in life．
