Life Can Be Good - Can't it?

Been feeling off these days.  I've made the mistake of looking backwards and then looking forwards.  Neither can do me any good.  My guru (yes I really have one) says I can only look at the moment I am in.  Why do I have such a hard time doing that?
 I have a very good life. I'm married to my best friend, have a darling dog, live in a great house, have wonderful children and beautiful grandchildren.  In comparison to even those in this country who have been without jobs (I really don't like mine but hey it's mine) and are losing their homes, I'm on easy street.
So why do I want to just sell everything and unload all this accumulated stuff?  It's like this giant burden.  Martha Beck and Geneen Roth both say to shed ourselves of stuff and stop buying what we don't need - it all just adds to our worries and really doesn't address the truth about ourselves.  We hide under the piles of stuff.  The good feelings we get when we buy something lasts only a short time and then poof it's gone only to be replace by remorse and regret.  It really doesn't give us the real thing we need - love and lack of fear.
Swami Nirmalananda says that most of us live a life of fear.
But she also says something else that I find the most comforting. "Nirahankaaram means free of egoism.  You don't have to prove yourself or even try to improve yourself.  You are already the 'new and improved version' of yourself.  You are the Self, consciousness-itself."  I need to remember that in a world that is always trying to make us believe we have to improve ourselves, planting the voice in our heads that we aren't worthy or good enough just the way we are.
