Hmmm - 1966 - 2013. Hindsight, which I don't always admit to, says that the less I did(to read and manage my investments) the better the results.
Male hormone wise this sometimes ticks me off - but then there is football plus a few good stocks I can't bring myself to sell.
Been a Boglehead for a while - lead sled dog is a Target Retirement (lifecycle index type fund) nowadays.
However - starting 1966 went thru Seattle broker, Denver broker, load, low and no low load mutual funds, timberland, gold coins, me and some guys from Littleton had a 10% each joint venture in a defunct Jamestown patented gold mine, dividend stocks, rental real estate, and possibly some I forgot. Read a lot of books and went to New Orleans chapter AAII meetings to hear guest stock guru's - Great pastries.
Some where in the 90's (1994 Bogle on Mutual Funds) gradually became an indexer/Boglehead convert - grudgingly admitting my company 401k (Bogle's Folly aka S&P 500 index) was beating the socks off my brilliant investment moves.
heh heh heh -low expense, low turnover, passive indexing with auto rebalancing works for me. But life is hard - Denver, Saints, Chiefs. Been thru losing seasons in all three places - now that they are doing better - who to pick.
