Reading the article and then reading the comments. I start to feel very confused. Do we need a huge debate about this? Some of us just want a higher degree and we just want to go to graduate school to do research. For me, I also love the people I have met in graduate school. It may turn out to a wrong decision? But we will never know that because we could not go back and re-make those decisions. Even if somehow one day I knew for certain that going to grad school was a wrong decision, so what? It was something I wanted to try and I tried it. I think I would regret more if I didn't try something I really wanted...
