$2.5 millon, Which strategy for maximum growth?

[Account Closed]

Hello Everybody, 

I'm 21 years old and have accumulated $2.5 million through e-commerce. 
I now want to diversify, I have around $1m in S&P 500, and want to use the other $1.5 for real estate investing.

My end goal is to build a Real Estate Empire and I feel like I am in a very good situation to do so,

I love working and I am not looking for "passive income".

What would you pros do in my situation?

William
