For me? Today is one of those days.
The important thing on these days is to be thankful and humble. There is no reason to brag and tell everyone how awesome you are at what you do. The key thing to do here is, ride it out and be thankful for what you have all around you. It is one day at a time and remember that feeling to remind you when you hit droughts because droughts are inevitable.
