how could I have made 2018 better?

Personally I think this is kind of a stupid question.  Why keep looking back and going over and over it.  Why not just look forward?  Well there is the whole learn from your mistakes thing.  I could have not done our will when we did.  I could have not bought ram an noodles.  I could have decided to not let my daughter have the foot surgery.  I could have done a lot of things.  But then I probably wouldn't have gotten a will done at all.  If it wasn't ram en noodles, it could have been something else.  There's no way I would have known about the foot surgery.  The infamous ear infection wasn't under my control in the first place.  Live and learn.  What's done is done.
