I began to wake up today

It could have been the exercise.
It could have been the water.
It could have been the sunlight beneath the partially closed blind.
It could have been last night's phone call.
It could have been imagining the second and third phone calls I never completed.
It could have been my dreams.
It could have been any one of so many different things. But I think it is because of the first reason listed above, in concert with looking forward to my own future. Plans three months out do have an effect on me. Now it is time to make plans one week out--for a boost--or more.
