Idk what I want

My husband has a great career. It allows him to travel, he gets paid very well and he can easily (and plans to) branch out and start his own business off of it. I'm so happy he got the ball rolling, that's definitely a huge milestone in our lives and I'm so proud of him for taking that step forward. But I personally feel so stuck. Like Idk what to do. I'm thinking about taking college courses for business but I'm behind because I never even finished high school (I'm 23) I want to look into the stock market like my aunt does, she's been a stock broker and financial advisor my whole life so she has experience and I want to learn some things from her. I also want to travel with my husband eventually or travel for work so I was looking into being a flight attendant or something as well.

It's so hard having all these random ideas in my head especially when someone asks what I want to do with my life or tells me I should already know what to do. I don't... My husband said when he was 23 he didn't know what to do and was kind of in the same boat as me but everyone else seems to have their lives together and I'm just like... Idk what I want....

I just feel stuck and behind in life.
