I think as humans we're generally interested in the following areas:
- Sex
- Death
- Greed
- Love/Hate
- Happiness/Sadness
So pick a topic e.g. 'GREED' ...hmmm how to incorporate greed into something topical? Well what about people's greed for resource? Their antipathy toward the migrant influx into Europe? Ramifications for the indigenous peoples in Europe? A little too heavy ...ok try greed for food in the West. The waste of food..the obesity epidemic....diseases from excess of processed foods?
If that doesn't float your boat what about choosing..'LOVE' : how about the risks of modern internet relationships? Has anyone you know been CatFished? Warning signs to look out for etc.
The key is to have a number of keywords and then let your mind wander and see where it takes you. Don't force yourself to come up with a result..let it flow ;-)
Thanks @g-no would pick a number from list and let it flow(grow, or rip)
