Three things I would have told 5 year old me:
1. Invest in Amazon.
2. Don't date anyone named Erin. Ever.
3. You're going to blackout on July 19, 2018. Wear a helmet.

If you are in your 20s:
1. Minimalize your shit. Your broke ass doesn't need that much shit.
2. Learn how to invest in the stock and/or foreign exchange market
3. Learn real estate
4. Stop trading time for money. Fuck that $12 dollars an hour bullshit.
