You need a certain kind of madness to want to work in a research lab, I suppose.

Not madness, no no. You need the perfect mix of brains, nerdiness, companionship and of course beer (or an equivalent).

Seriously though: happens to every single student. Maybe that's all the bad luck for you and your master thesis will go smooth! (it won't.) ;-)
Not to mention a PhD, where you're self-dependent and have noone to run to for help... very interestingly though, it is still fun!
