Check out this blog. It's long but worth the read. I stumbled upon this guy about a year ago when I was sick of spending time reading and researching which companies to invest in, how much, when to buy/sell, etc. Day trading is exhausting and difficult. My Vanguard funds are a secondary investment thing for me. I have a pension and 401k, but everyone also talks about how you will need more in retirement so I just started a basic Wealth Savings account. Currently invest in 3 Vangaurd funds - VTI (Total US Stock), VEA (Developed Markets - Europe and Japan) and VWO (Emerging Markets). I automatically reinvest all dividends. Very passive and simple and I could withdraw funds if I ever needed to for an emergency.
Lots of different ways to invest, this has been the strategy that makes more sense for me.
