What makes an idea great?

Anyone can have an idea but what makes an idea great?

Here’s an example of a great idea:

In Stockholm, a portion of the fines collected from speeding drivers is put into a lottery. Drivers who don’t have any offences are entered into the lottery and have the chance of winning some cash for driving safely. Motorists have received checks of up to £3,000 and the scheme has encouraged road safety. 

A great idea has layers.

Let’s break it down:

1- In Stockholm, a portion of the fines collected from speeding drivers is put into a lottery. 

2- Drivers who don’t have any offences are entered into the lottery and have the chance of winning some cash for driving safely

3- This then encourages more people to drive safely 

Layers create a great idea.
