Giving some thought

So I been giving it some thought and have been looking into finding a small business for sale, something in the area of what I enjoy doing, or if things keep going the way they are going and hubby continues to feel let down at work, perhaps him branching out into his own small business.  Sometimes I just can not shake this feeling we need change.  I get so frustrated sometimes, wishing I could work outside the home but right now I can’t with being a caregiver to my father.  Sometimes I do think about if I had the time what would I want to do?  What direction would I go?  With the new year approaching, I sometimes pause and think about these kind of things.  Once my children have grown and moved away and my father has past away (its a fact of life, it will happen one day), what will I do with myself?
