this might be a metaphor or five

sometimes you have to do boring mindless work.

because practice makes perfect, and practising is never fun, because all you do is chop chop chop, trying to clear what seems like an endless forest.

then the clock tells you that it's already 6pm, and you go home.

then you wake up, pick up your axe and start swinging again.

time passes.

you're hard at work, someone passes by, comments,
'what happened to all the trees?'
