Tell a girl that your an FI and they think you're loaded, little do they realise that you're actually less well off than you were as a teenager thanks to the unique way that flying schools are funded...
Anyhoo, back to the OP.
Something isn't right if you have been stuck in the circuit for 16 hours. My first suggestion is that your FI is an idiot, but not having met them, then I won't presume anything, however what is clear is that they have a huge lack of imagination.
I'm surprised that you haven't jumped out halfway through a circuit detail as you are bored beyond belief.
Just bashing around the circuit is not helping you. In fact it is now having a damaging effect, the fact that you are posting on here about it proves that. If your FI isn't smart enough to realise this on their own, then I suggest a change might be in order.
