Or we may not act in such a physical way, but let our free mind fly every where in the universe, then after knowing an infinity of new stuffs, receiving uncountable of new data, then what next?Try to apply those in our life? Try to act like what we admire?Without anyone to be responsible for, how free and amazing it would be.
Some people do have these kind of experience, by not setting any target, just go wherever there is a way out towards the world, to start their adventure without regret; instead of living like other people in a standard life cycle of studying, working, married, saving for house, car, pet and waiting to get old. They may gain or lose after all, but one day, they have to stop like Forest Gump stop running, take a break and find their way home. A place that always open to wait for their return, because there is our destination......our family.
