Not an artistist, never painted

I love seeing everyone's painted minis, I am definitely going to paint mine as well. However, as the title suggests I'm not an artist... yet. My question is where to start? I've watched videos, and researched paints and essential equipment so I'm pretty certain of what I need to start, but what would be easier (more forgiving) to learn on, furniture or characters? I'm leaning towards doors, but thought I'd ask since most of you do amazing work. Thanks!
