Whenever you get the chance, be the bank!
How do you start to be the bank? It's pretty simple. Here are 5 easy steps...
Borrow money at a low rate
Lend it out and/or invest it at a higher rate.
Reinvest the difference until you get to a point where you are playing with "house money"
Invest that money into an income-generating assets
Find a way to play (or create) "games" where the odds are in your favor for the long term (ex. Mortgage-Backed Securities for banks).
You can do this with a personal loan, line of credit, and as a last resort, with some credit cards.
It took me years to learn the above. It has taken me even longer to actually accept this as a way of capitalism available to all of us, not just the big banks.
Hopefully, you will take these jewels and run with them faster than I did. I'm still playing catchup out here...
The faster you master the above things, the faster you will become financially independent.
