Today, you won’t control the external events that happen. Is that scary? A little, but it’s balanced when we see that we can control our opinion about those events. You decide whether they’re good or bad, whether they’re fair or unfair. You don’t control the situation, but you control what you think about it […]If we can focus on making clear what parts of our day are within our control and what parts are not, we will not only be happier, we will have a distinct advantage over other people who fail to realize they are fighting an unwinnable battle.
