Indecision causes suffering. A line my first coach used a lot and that explains a lot of suffering I see in myself and others. I also used this to diagnose character motivations when I was in a fiction-writing group.
Another of his maxims: Why are you making it so hard? Said to myself whenever I poke my head up out of the gopher hole after several hours spent trying to figure something out. Taking a little walk, taking a break, getting some perspective – they all give me time to pause and reflect rather than overthink.
And this is one I’ve heard recently: Leave yourself alone!: stop beating yourself up , harassing yourself, etc. You’re fine as you are.
