Facing the Dilemma

Sometimes I wonder if twenty-four hours per day will ever be enough for me to do all the things:- I have to do- I must do- I want to doand- I'd love to do...Not necessarily in this order... 
Today I somehow managed to do all the things on the lists from the first and second bullet point. The thing is; I do them every single day. Yeah, my real life makes me do them with no exception.
Now, in the evening I finally reached the third and fourth bullet points' lists and I'm facing a dilemma. Which 'things to do list' to tick first. To be honest with you, I have approximately another three to four hours to do at least some things, but they are all quite 'time consuming' - in a good way.
I have to decide between:- re-reading the last proofread of my second novel and get the final 'finesse' to be ready for submitting;or- write Chapter Fifteen of my next WIP. 
I have also one more thing to do, but this one I'll keep as a secret just for a while more...
So choosing between three things isn't easy and, well, as you can see - I started on a completely different thing - on one that was not even on my 'to do list'... sheesh...
