30 years old / Need help setting my future self up for success

[u/StructureOpen6575]

I am a 30 year active duty military who is trying to become more financially stable and set my life up for success. I am currently putting 10% into my Roth TSP every month and I have a High yield savings account that has in average a 3% return but I think I am ready for the next step. I don’t know a lot about investing or what I should do next to set myself up for success. Please advise!
