Plants on Plants on Plants

I've been debating with myself with this the past quarantine, so like the past few months of so. I 1000% know that I don't have any room for more plants but I need to get another like string of pearl, or a succulent, or like Monstera or like a bamboo palm plant. 

Plants cost too much and I don't want to buy a cool plant and kill it the next day....Thats why I only have two snake plants succulents and two plants from my dad  I still don't know what they are but they haven't gone dry yet...
