I feel sorry for all that happened. The police in my location are nothing to write home about not to talk of the fire services.
And for this question,

What about you folks? Do you put any thought into what may go wrong, the risks that exist around you, and what methods or strategies you could employ to mitigate them?

Yes, I put into thought what might go wrong, especially when making choices I weigh the benefits and consequences of my choices before going ahead, and for eventualities, I have this imaginary scenario of what might go wrong in my head. Like getting fire extinguishers handy in case of fire outbreaks, learning to move on after a failed relationship happens, knowing my health can fail me at any time, and preparing for the worst while hoping for the best.

One thing that has helped so far is living a simple life, not depending so much on my possessions because they can be lost at any time, and learning to live without so many things that are not necessary though they are luxuries.

Thinking in such a manner has helped me to take life as it comes. If today is fine, I am fine, and if today is filled with troubles I expected it and I will do all I can to help myself.
Though you can never be too prepared least it will save you a lot in preparing your heart to face the ugly events when it arrives.

The other day our house almost went into flames as a result of high voltage from the power supply, I had to be a man for myself, I summoned up the courage and headed to the changeover, disconnected some wires before switching it off, before calling out for help.
If I had run out before doing that, I guess I would have been homeless by now. Because before people will come to my rescue so many things would have gone wrong.
