1) There are several secrets to becoming a successful #investor and most are hiding in plain sight. 2) This many sound like a cliché, but it hides a simple truth: buy quality companies. When I started #investing, I didn't feel like I could identify quality, so I bought a subscription to @TheMotleyFool and let them do the heavy lifting.

1/ OK Twitterverse. Here's my most costly investing mistake and what I learned from it. Back in Aug. 2007, I bought my very first shares in $NFLX for a split adjusted cost of $2.44. I didn't have much to invest at the time, so I put down my entire $250 that month on $NFLX shares. 2/ Mind you, being so new and wet behind the ears, I didn't yet know what type of investor I was. I heard people that "sounded" much starter than I was say, "Take your money off the table, and play with the houses money." Note the comparison to gambling (I did NOT at the time).
