Karl, 57, (married 30 years) “This is great marriage advice and, really, great life advice. You can only handle so much stress in one day, as an individual and as part of a family. As we’ve both gotten older, we’ve realized that we’re more capable of choosing what we want to stress over, and that’s what we do. What might have seemed like a huge deal 20 years ago — an annoying neighbor, or unexpected car trouble, for example — has really been put into perspective by all we’ve gotten through together. If you can accept that you’ll have stressors in your life, you can train yourself to decide which ones you’ll let affect you and your marriage. And, more importantly, which ones you won’t.”
How many times in a day do we let the little things that bothered us add up to end up with a bigger problem than what it really was? Be conscious of the stressors in your life and choose your battles. This is a sign to choose to let go of the insignificant irritations in your life so that you can find more space for peace; so that the frustration doesn't leak into your relationships and ruin the good thing you got going on.
