I was having a day like that today - the weather, my boss, an incredibly painful flu shot all came together at once and made me feel down.
But good thing about being a positive person is knowing how to fight these things off. It comes naturally - like, planning a gym visit and a shopping trip and starting looking forward to it. Or getting some annoying task over with - and feeling relief. Or receiving a response to a request you've submitted weeks ago after a reminder you just made to the guy without much hope of hearing back.
Silly tiny things like that do contribute to improving moods once you start noticing them. Oh, and green tea with mint - turns out I am crazy about it! Who would have thought!
My special thanks go to my friend Sairah for not giving up on my miserable whiny self and trying to improve my mood. It worked! ;)
