The 80/20 rule

I know the 80/20 rule.  Balance and healthy lifestyle is maintained if you do/eat what is right 80% of the time with allowing yourself to 'fall off the wagon' once in awhile.  Keeping this balance rule in mind, life continues and you don't become a fanatic in anyway.
I know this.
So, I have to question myself WHY do I feel so GUILTY when I dip into my 20% reserve and eat a modest portion of salt and vinegar chips? A small portion of French fries?  2 cookies?  Yes, even a full bagel.

I feel frustrated that as I am working hard at the gym, and the progress is there but not in relation to the hard work I am putting in.  Therefore when I eat junk food I say to myself "80/20 rule-- yes BUT you SHOULD HAVE KNOWN BETTER".  Where does this self imposed guilt come from??

I was a musician for more years than I have not been.  When you are a flautist in an orchestra, you must be perfect because if you are not, there is no hiding.  Everyone knows that you messed up.  You did not pull your weight (pardon the pun), you did not work hard enough to perfect your part. You let everyone down and embarrassed yourself as well.

Good job...

How many times did I hear from teachers and conductors that "a chain is as strong as it's weakest link"? 

Is this why I am harder on myself than in other areas of my life?  I love being a homemaker but I don't NEED to find perfection there.  The ironing can stay waiting for me for a week.  I can walk past a pile of papers waiting to be filed.  But regarding myself, I must not waiver from the sense of perfection that I have placed on how I want to look in my favorite pants.

Ok, so now I have had this great, aha moment.  Now what do I do with it?
Give myself a break and realize that the stress related to being in the spotlight on stage is over and really, no one will notice if I continue to be healthy using the 80/20 rule.
That is a start.  I also have to remember that right now, I DO look great and not to worry so much about NOT looking great.  I don't need to live with self imposed pressure.  That's just a waste of energy and a good dose of guilt that I could be saving for the kids!  Like for homework or practicing or writing thank you cards or not making their beds, or....
