What are you going to do in the next 15 years? Where will you be? Would you be famous? Would you meet your inspiration? Would you accomplish what you want to do now? Would you be on a totally different path from what you expected to do? Would your best friend stay your best friend? Is your best friend who she/he used to be? Where would you be living? Would you have a bigger family? Would you be richer? Would there be robots dominating the world? Would 2012 strike in the year 2050?
Close your eyes and try to view the future.
Pretty vaguely austere, huh?
