Atlas was permitted the opinion that he was at liberty, if he wished, to drop the Earth and creep away; but this opinion was all that he was permitted.
In some types of music I'm working out all the chords one bar at a time - the whole structure, because it's about that. And there are other pieces which are really about - okay, the melody is going to start here and play through to here.
I think it's probably best to work out in the morning to get it out of the way. My ultimate top tip is to drag yourself, even if you have to roll yourself out of your bed and in to a sit-up - it's really not that bad once you start.
