Speaking or writing about “success” is always very successful :) with teens and adults. Everybody wants to be happy, everybody wants to succeed. But what is success? Ask your ss to close their eyes and think/meditate a bit about their picture of success. You may also want to put some nice music on while they are dreaming. Then let them share their ideas. Stick different quotes around the classroom and give your ss some time to walk around and read the sayings of famous people about success. When the time is over ss say what they remember. Then give a worksheet to each of the ss. Present some new vocabulary if needed (e.g. set a goal/an aim, achieve a goal/an aim, reach a dream, overcome obstacles, fail, succeed, take an opportunity etc.) Let ss discuss the quotes. Good home task would be to write a composition about success or any famous successful person.
