My father lost his job when I was in high school. My parents did random odd jobs to support me through high school and college, I saw how much they toiled so that I could lead a better life. Got into one of the best technological schools in my country, did some good research, got papers published, got good figures on my GRE and TOEFL but after graduating with a BS relocated and took up a development job at one of the biggest software firms in the world so that my parents finally have it easy. Slowly realized this ain't for me - I missed research, so decided to apply for PhD although it probably means financial frenzy all over again. Was amazed to see how supportive my parents were, want to make them proud and happy - that's all.
