I might be cranky before I eat my chocolate. I am happy while and after I eat it. I am dull and gloomy a while later as the sugar crash sets in. But a little more chocolate can fix that. So if you have some chocolate, just hand it over.
Be confident. Too many days are wasted comparing ourselves to others and wishing to be something we aren't. Everybody has their own strengths and weaknesses. And it is only when you accept everything you are, and aren't, that you will truly succeed.
