I am not 100 % minimalistic yet but I am getting there. I used to have so much stuff (clothes, books, make up, decorative items etc) that I barely couldn't breathe. Then I decided to get rid of most. Some things I've sold on ebay, some I've given to a friend and some I donated or even threw them away - like lipgloss cause I wouldn't want to give that to someone else, for obvious reasons!
I hope this video might help you to start your journey as well. Maybe just go through your clothes ones. Or throw away that awful lipstick you've been holding on to for years because "you might wear it someday" :)
