I feel that everytime I reach a point (with much efforts), immediately I am asked to take a step further. I spent many months studying Metropolis algorithm, and just when I began to understand it, I was challenged to improve its efficiency. I have tried to understand how to do research, and just when I start having hope to understand it, my second deadline is approaching. Just when I think I know something on structural reliability, I am expected to answer questions on that topic. Just when I begin to enjoy living on my own, I am expected expect to … start a family ?

Maybe stretching is good for growth, but sometimes I feel rather tired and doubt whether I am up to the task.
