Life is very busy, one get lost in his daily routine so much that he don't realize what is he doing and why. Its always good to take break from the regular routine (job tension, growth tension, work life balance tension ...).
Go out with friends (preferably other than office friends). Friends act like a mirror and make you realize what exactly are you doing in life.
Travel to realize how easy/difficult life is for you by just feeling the way people are living outside your world. Travel always test your physical stamina and gives you so many distinct flavors in a short spam of time. For me globalization is hurting this part of travel (same things are available everywhere but its just an option one can ignore any day).
