So what if you focused on what you can change? That’s where you can make a difference. Behind the Serenity Prayer is a two-thousand-year-old Stoic phrase: “ta eph’hemin, ta ouk eph’hemin.” What is up to us, what is not up to us. And what is up to us? Our emotions Our judgments Our creativity Our attitude Our perspective Our desires Our decisions Our determination This is our playing field, so to speak. Everything there is fair game. What is not up to us? Well, you know, everything else. The weather, the economy, circumstances, other people’s emotions or judgments, trends, disasters, et cetera.
