Afraid of change
It seems like all life wants to do is change. Why cant life just be predictable and consistent. The stock market is changing, people are passing away, new babys are being born, you're getting fired, or your getting hired.. all life does is change. Why is that? Why does it seem like we can't just get that stable, comfortable, predictable life? Why is life always striving to be different, to grow? Why is life always changing?
The question is not why is life always changing, the question is why aren't you?
Embrace the change. Comfort breeds complacency. If you feel like life is changing too fast it means you're not adapting fast enough.
