Just this morning, I was making a list of things to worry about. So far:
1. Lethal heat waves and extreme storms will prevent me from going outside to take photos.
2. Putin is going to push the Big Red Button, and it will be too radioactive to go outside and take photos.
3. Civil war will be followed by a complete breakdown of society, and it will be too dangerous to go outside and take photos.
4. My four mechanical SLRs will all break, and I wont be able to go outside and take photos.
5. A collapse of the financial system will wipe out my life savings, and I will have to move outside and live in a tent camp and eat whatever I can find in dumpsters.
Now, all I have to do is make sure the items on my list are in the right order, so I will know which ones to worry about the most. ;-)
