Camping- living in a small tent when you could be comfortable in your own home. Teaches you sacrifice!
Mountaineering- Risking life when you could be comfortable in your surroundings.. teaches you empathy.
Doing engineering when you could have taken Arts/Humanities. Learning how to take torture (in case you are captured by enemy soldiers), what with all the entrance exams..
Doing MBA.. Working harder than you have to.. a lesson in itself. Also, how to do group assignments when half the group is missing.
Becoming a professor.. discovering how people are not interested in your lessons, and that's a lesson. You were the same when you were a student, so it's a deja vu of a different kind!
