What if I won't enjoy our planned afternoon of gaming?
What if I suddenly grow sad and apathetic in the middle of our hosting friends?
We have done really nice things with that wall.
What if my side-effects screw me up, and I won't even care?
What if I cannot pull off my chosen career?
Cannot be a career academic?
Cannot get a permanent position?
What if the research I do is not good enough?
Not interesting enough?
Not published enough?
