where to start investing so I can quit step away from my job ASAP

[Skip Gilliam]

A little background on me, I'm 38 been with my current company 22 years managing a large retail business. I get paid fairly well, $90,000+ annual salary but I'm just exhausted with the hours, nights, weekends and holidays and stress from daily operations. My wife has a better career, has a higher salary than I do , well over 100k annually and we collectively have roughly 800k in retirement accounts 401ks and stocks. We are in good shape financially but I want to transition out of my stressful career and on to something better. 

I'm want to start investing in real estate so I can generate enough income to leave my job and have more family time. Looking for advice on where to start and how realistic is it to think I can start earning close to my current salary within the next two years in real estate? 

Thanks for any advice!!
