It seems like every day is imperfect when working on my website and my business. 

The reason may be my higher expectations of myself rather than my actual productivity output.  I say that I will do this, this and that today but in the end, I only do one of the items. Is that really so unproductive? 
I think that as a human race, we put expectations on ourselves that are so high only because it is natural way for human beings to be. If Madame Curie didn’t strive to understand radioactivity and radioactive isotypes where would be today in nuclear medicine.  She died from overexposure to radioactivity from the samples she carried around.
Expectations of striving forward are what has moved the human race forward so as I like to say, Imperfect Action is better than no Action  because you are always moving forward. It may not be as fast as you wanted but as long as it is progress forward, you should give yourself a Gold Star!
