Virtue or Vice?

Is this a "True Confession" or a "Badge of Honor?"

Sometimes it is difficult to say if something is a vice or a virtue. If I read more, I fill my mind with good things, but I am tired the next day and may accomplish less. 

But if I sleep more, I might get more done, but at the expense of being bored and missing out on a lot of good things I could have been thinking about.

I am not sure if this is my guilty pleasure or a practice of sacrificial self improvement. It might not define me, but it certainly does describe me.
