Get out your camera...
If your characters don't travel much, here's a chance to get them to do just that. Make a list of all the places your character wants to visit or doesn't want to. Then answer these questions as they travel there.
- Who will they meet?
- How will the interact with the different people they come across?
- Will they take anyone with them?
- What happens if they run out of money?
- Where will they stay?
- How will they travel? By car, plane, boat, etc?
- What will the bring along?
- Will they try something new? Like a new food or go skydiving?
If your character lives in a fictional world, do the same thing, but in that world. Or have them visit this world. Whatever strikes your fancy.
