Something strange is going on with me. Today is Saturday, but I have so much energy, power and willing to action. What is it?

I think it is common deadlines when we plan our tasks inside one week. So either I am doing everything planned today or I will be total loser when the week ends.

Or it can be my personal type of energetic waves in organism. During typical days I am average worker, but some chemistry inside make me so energetic today. However I am going to user it fully.
