I was 23 when I started trading with money my father had saved for my MBA admission. I kept buying Reliance Industries on every dip because a friend told me a "big breakout" was coming. Instead of admitting I was wrong, I averaged again and again until almost ₹1.8 lakh disappeared from my account.
The worst part was telling my father. I expected him to slap me, but he quietly opened his old steel cupboard, took out my admission papers and said, "Money can come back, but don't lose your direction with it." I still remember that sentence more than the loss.
