i came up with several different ways to interpret this quote; life is messy, so always take every opportunity to learn from your mistakes as well as your successes // for me being messy extends from not managing to put away my clothes to how i figure out how things work by taking them apart (including electronics, people, relationships) // if things in your life are 'messy' you should take a look at the reason, maybe its awesome and you should be proud of that or maybe it sucks and you should learn from it.
but i felt like all of these analysis' fell flat. while all of them are true for me and probably you too in some way or another they just don't quite cut it.
so i'll leave it up to you to interpret how you'd like. I do know, even if you feel like a mess its ok, because you'll get it figured out.
