To go against the current a little bit, hold off on investing in the stock market as of now. The market is likely to turn downwards within the next year or two. There are too many indicators pointing to this.
Hold off and wait for the major indexes to lose ~40%-50% in value, then invest. During the 2008 crash, the main indexes and stocks lost ~40%-60%, and treasury bonds ~8%-10%. Save your money now and invest when markets start to bottom out.
