At times like now(bullish), do you continue to grow your position or wait for dips? I think there is great long term profit to be had in people allowing fortunes to grow in long term index funds, I just wish I was one of the people who could take advantage of it. My niche revolves around VIX futures contracts and their effects on equity index futures - so very short term(intraday).
Most of my investment is in my 401k, which I max out. As such I'm dollar cost averaging and not otherwise thinking about it (except my last paycheck in December is a mini bonus). My day job is writing computer programs. When I get home every night I have dinner with the family, play a bit and put the kids to bed. This makes it easy to ignore the stock market day to day: I have better things to do than think about it. Once a year I check balances, decide I can't retire yet (won't happen for years) and forget about it.
