plant life {succulents}

I have come to the conclusion that succulents aren't for everyone, even though it's been said they are the easiest plant to keep... & that you cannot kill them, but guess what... I killed them, A LOT of them!
I put some in really cute corks for magnets & the rest in this... & they are now all dead! 
I hope I have my grandparents & mother's green thumbs, but I am not starting off so great.
Obviously I did something wrong & I must try again because they look great... maybe fake ones will do?
yes... I need to dust...
