On an investment note, I have made one individual stock purchase in my life and that resulted in a loss of $200 during Snapchat's IPO. It's a petty loss but enough to teach me an important lesson -- I am not as smart as I think I am!
From then on it's been nothing but TSP c/s/i funds, VTSAX, VTIAX, and some bond indices.
In regards to real estate, if you want to get into that market but don't want to invest and manage individual properties -- consider a REIT fund. The only thing is that they are tax inefficient, so may consider using them in tax advantaged accounts such as 401k equivalent, IRA, and 529.
I am patient awaiting Impossible Foods to go public so I can repeat my past mistakes.
