Don't lose an arm. We'll watch you even without shark photos, ok. Let's just calm down.
And the troubles I assume are academic? Well, keep a stiff upper lip! As Nietzsche taught - to overcome difficulties in the greatest achievement in self development (or something around those line. What doesn't kill you, makes you stronger)
oh no, sorry - I meant I have big troubles to take a SHARK photo for you, because local shark exhibits are not very photographer friendly and I would need better lens to shoot something nice in Berlin or Vienna
