I'm definitely not an investor, nor do I know what I'm doing but...
* 401k, maxed to what my employer will match
* Stocks just for fun
* Bought a house when the market was extremely low
* Invested in myself; getting a Master's degree through my employer's gracious reimbursement plan
My father always told me to start young; max out the 401k and put even more away just in case. I wish I'd done more of that, as the longer I waited, the harder it became. Thankfully I started the 401k very early and never knew what I was missing. It helps to not see the money at all; checking on it every once in awhile instead.
