Am I allowed to reapeat any gratutudes? Ever? What if I'm super grateful? I'm not sure how long I can think of original gratutudes, but we'll see!

Today:

1. Clean running water. I must say, I'm very grateful for not having to bathe or drink very much pollution. Also for not having to fetch it, or fight for it. Super double plus good.
2. Toilets. Not possible without #1 (Outhouses are just sitting while shitting in a hole.) I am really thankful that I don't have to deal with the filth that I create. Whoever does that for me, thanks!
3. Convenient food. I have the feeling I could be subdividing this in to 100 different gratitudes, but let's just say that despite my reservations about some farming practices, I'm very thankful that I don't have to slaughter animals for food. I don't have to tend acres of crops, yearly canning, daily feedings and watering... Hell, I don't even have to walk very far to find a grocery store.

Does anyone else write down gratitudes or something similar in order to do good for your mind?
