How can I put you off when you're a matter of urgency?

Minimalism is all well and good and really suits some people's homes and spaces, its sophisticated and I must say it does look pretty darn fancy. But as far as my bedroom (and my life in general) goes, minimalism just doesn't work. I largely hold my hoarder of a mother responsible for this- her argument for keeping practically every little thing I've ever been given because of the 'sentimental value' means I own far too much stuff for minimalism to really be a viable option.

For the last few months I've survived with fairly bare walls (by my standards at least); there were originally 4 pictures on this wall... but I'm a girl who used to plaster every millimetre of spare surface of space with photos and posters by so this frustrated me so, so much. My surroundings affect my mood so much, and plain white space just made my mind feel pretty bleak. I need a good splash of colour and a bit of creativity to wake up to in the morning and spur me on for the day. Otherwise I wake up feeling a bit like 'Oh, is this it?'. Rebelling against the 'no shoving tonnes of holes in the wall' clause in the contract for the flat has done my mind the world of good. I now, finally, feel like the space is mine and it fits my eclectic (yet freakisly accidentally matching and coordinated) little personality so much better. Give me an overcrowded wall full of anything and everything over a pristine white space any day. I was never very sophisticated anyway...
