Gratitude Triggers
I started doing a thing where if I see it's 11:11 I stop what I'm doing and just think about things I'm grateful for.[^1]
It turns out this is great, and also there are many times in the day that have similar symmetry. So now I also do it if I notice it 9:09, or 14:14, or sometimes when it's 6:09, or 11:01, why not – with enough flexibility you can find multiple sympathetic times every hour.
I recommend it.
