Trying to live a "balanced" life

How are we supposed to live a "centered" life? Are we supposed to be good at work, relationships, spirituality, family, community, take care of our bodies and minds and then try to balance all of these things and find a "happy medium".  I can barely find a way to balance one or two of these things and I can't even do that! Is life a cruel test designed to drive us all to madness? Some days I think it may be. We should try to "better ourselves" and "keep learning". I guess that's all we can do. Hopefully some day we can find a way to master life. The problem is....I think it will be over before we know what hit us. Good luck. That's my thought of the day.
