I've always been of the mind set that in times of uncertainty you should dollar cost average in to companies you believe strongly in. so depending on what you're budget is for investing divide it buy 30 or 90 depending on how long you want to spread your money out and than buy that amount every day the market is open.

Always record of your own notebok, to remind yourself regard the purpose of invest into this stock, the reason that you invest to this company have to remain unchanged when you decide to leave it. and long-term always win at the end, especially at here, the U.S market.

Not truly understanding penny stocks.
Got hosed. Got wise and Got to studying about buying volatile stocks.  Hindsight is 20/20  but I Digress. 
Still Very Important lesson learned...
Do the DD on Everything and don't fall victim to what people say is a good buy because in the market no one can predict exactly what's going to happen.
Only trust your DD and if it happens to coincide with your  research you maybe on to something. Trust in your self and know when to take profits over greed.
Happy Holidays to my fellow MooMoo's!
