Isn't being content what we all would like? I don't think that people who are content in life have everything go swimmingly for them. It's all about their perspective in life, isn't it?
My life is better when I don't feel like I have to control everything. Thankfully, I'm way past that now, though it creeps in from time to time. At those times I am not content.
My content comes from knowing that my God is Sovereign. Romans 8:28 states that ALL things work together for good for them who are in Christ. Knowing that God is in ultimate control helps me to not feel the pressure of having to make things right. I can just do my best. Things will work out eventually.
So yes, when I relax and allow things to flow, I find life well worth living!

I can enjoy the smaller, and finer things here for me. I can "not sweat the small stuff" that others carry about and try to dump on me. It's a good perspective to have, imo.
