There is a difference between minimalist decor, and lifestyle. You can enjoy a cosy home but still follow minimalist lifestyle principles.
A few things I found helpful...
As some posters have mentioned - ‘The Minimal Mom’ YouTube videos. Some very good ideas there.
If you're stuck with where to begin, start with your car (if you have one). It's a small space that can clutter up very quickly. Keep the absolute essentials in it, and remove everything else. Every time you drive home, clear out anything that doesn't belong in the car before you go inside. Conquering this will give you a boost to begin to tackle the house.
Imagine that everything you own is silently communicating something to you. 'I need tidying' -'Clean me'- 'Fix me' - 'I don't belong here' - 'I need mending';- 'I'm too squashed in here'; -'I need a wash'; -'I'm waiting for you to sell me'; - 'Why have you left me here instead of putting me away?' Before you buy or bring anything new home, think about what it will likely say to you week after week; and is it worth owning it (or keeping)? Based on the idea that what you own ends up owning you.
As you declutter, don't plan to sell the stuff on ebay etc. You're unlikely to get around to it, and it will cause you more stress. Either bin it or donate it promptly to a charity and feel good about your generosity. Eventually you'll realise that the space and clutter free environment is worth more to you than the proceeds of a sale.
The thirty day challenge is a quick way to start in the home. 1st day of the month get rid of one item, 2nd day get rid of two and so on. By day 30, you will have disposed of 465 items. Next month start again with one item. Continue for a year and you'll be 5585 items lighter.
