I am already 26 years old :) and still striving to finish my studies as a "self fulfillment" thing. Yes, that was my concern before. .but after I get to know God and love Him deeper, I learned to take Life as having a real purpose why we exist here on earth. It's not just about Me or Us dreaming and getting things that definitely are fleeting. It's all about Him that we need to know so we could find our real purpose of being existed in this world.
