Came to the U.S. as an immigrant in 1968 from a poor Asian country with only $100 in my pocket. Took advantange of 401-K savings plan by contributing 10% of my pay. My employer matched the first 6% savings (50 cents/dollar saved). Did not know anything about investment so 100% of 401-k money was invested in index 500. No other savings except 401-K. Retired in 1999 at 55 years old with about $1.2 million in 401-K and $450,000 lump sum pension which I rolled over to IRA. I invested this money in bonds and only buy equities (small cap index) whenever value drop to at least 50% of its high. I made a lot of money by investing in small cap index (ticker, IWM). Because of the risk involved, I don’t buy individual stock.
Peer-to-peer lending ($1,440 a year): I've lost interest in P2P lending since returns started coming down. You would think that returns would start going up with a rise in interest rates, but I'm not really seeing this yet. Prosper missed its window for an initial public offering in 2015-16, and LendingClub is just chugging along. I hate it when people default on their debt obligations, which is why I haven't invested large sums of money in P2P. That said, I'm still earning a respectable 7% a year in P2P, which is much better than the stock market is doing so far in 2018!
