Oh shit. The discovery that my maths is worse than I thought is made even worse when I discover that I’d totally miscalculated what was in my bank account.
Next year I’m earning money, screw the career attempts my priority is earning actual money.
Edit: And then there’s that other feeling which comes from realising that my maths wasn’t actually out, the bank simply decided not to pay the money into my account until after it had been paid out…and they charged me for the privelege…
