And, i just think you are only underestimating the amount of knowledge that have gained back home. Stress and Experience does bring one's maturity to a whole different level, but its not entirely correct to say that you learned more in US in a year compared to your 19 years in Nepal. Culture, Language and Nepalese values surely cannot beat the US Driver's License or  using a Vending Machine or even earning your own living. As a matter of fact 90% of the English was taught to you back home and yet you still think you gained nothing from Nepal?

Give me a break for God's sake!
