Succulents!! 🪴

Is this thing healthy? Will it keep growing? I don't think I have much of a green thumb. I've had 2 plants a time ago and killed them both.

It lost the big bottom leaves that were mushy (they were like that when I got them) and I’m clearing away all the dead ones. These top leaves are very firm. I don't water it much. Never had these before; they were a gift. I usually Google these things but it's hard to know if I'm on the right or wrong track until it's too late.
