Ram gets rid of his lucky coin at the end of the novel Q & A. What does this gesture mean?

In Vikas
Swarup's novel Q&A, which was later adapted for the screen as the
Oscar-winning film Slumdog Millionaire, the , Ram, has a coin which he
flips whenever he needs to make an important decision. Ram thinks that the coin is lucky, even
though he's an orphan living in the most wretched of conditions in the world's biggest
slum.

Ram's estimation of the coin seems to be vindicated when he goes on a
TV quiz show and becomes the biggest winner in the show's history. However, Ram's luck soon runs
out as he's accused of cheating on the quiz questions and ends up being arrested by the police
on a charge of corruption.

Thankfully, due to the efforts of his lawyer, Ram
is released from police custody. It is then that Ram realizes that luck comes not from so-called
lucky coins or charms but from within. Besides, the coin was double-headed, and so it was never
really much use in the first place. So Ram throws it away. From now on, he'll make his own
luck.
