I don’t have sayings per say, but when things aren’t going well, I always remind myself of all the things I have to be grateful for. I remind myself that i’ve gotten through worse. I remind myself “Everything is temporary.” Impermanence…nothing stays the same. And boy is it true. Good times, bad times, good relationships, bad relationships are always evolving, ending, changing, etc. Being ok with this concept has helped me a lot. Not always easy.
Living in the present helps a ton too. I once heard this quote from another villager and it sticks with me: “Expectations are premeditated resentments.” Boy do I use this one a lot.
