We all run into times where we end up in a slump. Something in our life is difficult, sad, or frustrating. When this happens most people tend to slow down and focus on the hard thing in their life. Their life revolves more and more around the difficult aspect and their world shrinks. The next thing you know you feel miserable most of the time.
When you see this happening the solution is usually action. Taking some action to get you moving forward. The action may or may not be directly related to the hard thing in your life. The action may be to take time to sort things out and reflect. It may be taking the time to grieve a loss. And it may be excercise or working on your dreams. But if you are having a difficult time in your marriage, and you set aside time to work on your hobby or your dream, you will start to feel better. You feel better about yourself and you feel better about your life. Soon you can start to see that there is still sunshine in your life, even if there are clouds.
The really great thing about this is that as you start to feel better about yourself it will spill over to other areas of your life too. Then maybe you can take some action where the hard thing is concerned.
