I just came back from a restful week of holiday. I'm refresh, and full of energy, yet I'm tired and cannot wait to sleep.
“Why?” you say? My son decided to wake up this morning at 5AM, so right now I'm tired.
Lesson of the day
Don't mix you long term energy levels (mine are really good at the moment) with your current energy level. Energy levels change every hour, after every lunch, and in my case mornings are more energised than afternoons.
