Lately over the past year sometimes I will wake up to a day that's unusually full of light (in a spiritual sense) meaning that spiritual endeavors will succeed with ease and its a good day to daven at length and learn in depth.
Occassionally I will wake up to a day that is particularly dark and heavy, I know the whole day will be one big effort just to keep from stumbling, with no thought at all to trying to grow. (A grin and bear it and it will be over kind of day--I'm not on the level to 'turn such days around davka!')
The first few times these days occurred to me, I wasn't aware of what was going on, but I've come to notice when these rare days do come up, and to try to go with the flow of the day.
Today was a novelty in my admittedly limited experience in flavors of special days. Today was a day with a lot of potential, but no inherent leaning towards being a good (or light) day or a (dark or) bad day. It was just a day that was waiting to be really something, and the something depended on what we would bring to it.
So I took the time to pray and learn and I'm trying to keep with it throughout the day. I asked about this and was told by one Rav that it was a day of personal spiritual potential, but with all due respect to the Rav I asked, (and I hold him in the highest regard) it didn't feel like that when I woke up. It felt like a very big day for the klal, for all of Bnei Yisrael.
So the day is up for grabs, bend it and twist it according to your will, hopefully pray and learn a lot and the day will bear special fruit for us all as a nation, as a family.
May every day that greets us be a day of light for Bnei Yisrael.
