I'm a firm believer that colour is an absolute necessity in any space. Yes, while the argument still stands that simplicity is truly beautiful -- the one way to add diversity to any home, office, or workplace is truly kept in colour.
Whether you're headed for tonal bookshelves, a turquoise kitchen, or creating a central moment in the lounge room, you can paint an old desk in need of an upgrade, reupholster a piece of furniture you've fallen out of love with, or modernize a painting you've picked up at a flea market.
In my mid-20s crisis overhaul, I've decided upon one strict rule that I refuse to bend on: I have to be obsessed with every piece that enters my home. A notebook, teacup, art piece, even down to the crystals, the pens, and even my beloved typewriter. Each item needs a purpose, even if that purpose is just to make me incandescently happy when I pick it up or spot it on my way out the door in the morning. By creating this rule and abiding by it, you are also limiting yourself to only seeking the best items -- and other than the obvious benefit of limiting unnecessary spending, you're also allowing yourself the space and freedom and permission to have a treasure hunt to create that beautiful nest you're always cozying into at the end of the day.
