Sometimes I get down on myself. You have a vision of the way you want things to materialize, but things don't always go according to plan.
I constantly have to tell myself to breath. Analyze the situation. You can't force it. Things have to unfold on their own. All things in their due time. No matter what our plans are, the universe sometimes has other plans for us. We can throw a tantrum, get upset, or just accept the situation and move forward at our own pace.
With a little trust in the universe, and faith in ourselves, all things eventually work out as they should.
The only constant in life is change.
