Here are a few good thoughts that one of my friends just sent me. I think it is very valuable.
Sometimes life will present you with an unexpected detour. Sometimes you’ll spend a lot of time and effort, and end up right back where you started. Such times are no reason for despair. Rather, they provide an opportunity for renewed determination and commitment. Sometimes, things will not go as you planned. When that happens, keep in mind that much of life’s richness comes from its unpredictability. Rather than cursing the detours that life throws your way, explore what they have to offer. Even though you’re not moving in the direction you intended to go, you can still make positive progress.
