A.k.a Sunk Cost
There was once a client, who wanted something fancy. So he hired some MBAs, and then they made some multiplications and divisions. And then, those multiplications and divisions were called something space age. RoI, RoCE and something I don't remember or care about. But they got Lamborghinis and penthouses. But some are idiots, like me, who thought this is a universal bullshit . Bullshit you can apply to anything. Even love. Your passions. Stupid brain ! There were some years when I was a paranoid. I was mad. I was investing. There was a June, when I got up at 4.30 am in the morning , sneaked out of the house and into my car. Drove my half asleep self across Delhi to pick up someone who had made an investment and take her to her house. I pride myself to have got her there in time. Then slept in the car near her home for 2 hours. Waiting on the road. And waiting....and more waiting....until my 7th call got answered around 10 A.m. Lovely sauna.
