I want to be wealthy and comfortable

I Im a stay at home mom of a one year old. I live with my fiancé at my moms apartment. I’m 19 and he’s 24, a teacher and bartender. He approximately makes 45k a month, enough to live, but not enough to do all the fun things we would like to do. We both want that wealthy, comfortable and luxurious lifestyle. He already has his career going for himself and plans on working on being a principal in the future. Anyway, I know the life I want to give to my daughter and what I want for myself and fiancé and future kids. How can I get to that point? What do I do? What degree and what do I go for in college? Im not a materialistic girl. I don’t own any expensive brand clothing, or shoes. I want to be able to give my kids and family everything they would need and want. I want to travel, give my daughter amazing life experiences, own my own car, have a jet ski, go on family trips. There’s no step by step manual I know.. this might seem like a dumb post but since I’m young now I want to start working towards the lifestyle I want for my future. I wanted to become a dental hygienist but I don’t think that would make enough money to do the things I’d like to do
