I can't choose between these 2

I actually can't choose between being a flight attendant or a show home person idk what they're called, so basically I would be a flight attendant cause it's they get to go on planes and I love planes  but I feel bad because my sister wanted to become one but she was too short, it's kinda funny but I don't know if like in the future I became a flight attendant would she like secretly hate me. I hope not cause I really want to become one and then becoming a show home person is just a safer option you know cause I don't need to worry about anyone holding a grudge against me for the rest of their lives.I honestly don't know which one to pick but I have like a few years to decide so it's fine for now.
