Confession time

Can I make a confession? I'm not very good at gardening but I really want to be.I like plants and flowers but I can't seem to keep anything alive.I killed cactus. And an aloe plant.  I think that's some kind of special.I blame it on lack of natural light in our house so I'm trying round two of houseplants.This guy took the place of my aloe that I killed.  Actually, I'm blaming my daughter on killing the aloe.  I told her it was good for healing wounds and she kept hacking away at that thing until there was nothing left.This guy is in my laundry room {lets pretend the humidity will help}. I moved him closer to the window in hopes that he will get some more sun than the hacked up plant by the laundry room sink did. 

This is the pot that my cacti were in.
They died a slow death.

I'm trying something new and am only going to water them with fresh lukewarm tap water and not the soapy hot bathwater I was watering the cacti with.
So far so good.

Any other tips?I really want to not kill everything I touch. I'm starting to take it personally.
