30y/o 9-5er looking to learn RE investing

[Ralph Lauren]

I’m a 30 year old veteran of the US Army, working a 9-5 (12-9), with a stay at home wife (temporarily) and two children. I make about 70k, which about 60% goes to mortgage etc. I’m proud of where I’ve gotten to at this point in my life, but I do want better for myself and my family. I want to be able to teach and pass things onto my children. I just don’t know where to start. I will appreciate any input, thanks.
