Kerriella, forgive me if I repeat anything that is not news to you, but your posting moved me because I very much understand how you feel, from past experience. Penny stock investments will never be for the faint of heart. There are big losses and big gains. Anyone would be a fool to tell you that there's not a chance of having huge losses, if you don't protect yourself.
The best things I ever learned about investing were stops and limits in buying and selling shares. Scottrade has great info about this on their site, although not everyone likes buying shares through Scottrade. Basically, rather than watching the prices go up and down all day, you determine the lowest price you can handle your stock going down to, as well as how high you'd like to see the stock go before you sell. These are extremely helpful protective measures, and unfortunately a lot of people still do not ever use them. That, in my opinion, is what really makes people lose their shirts on stocks. Stops and limits are almost like insurance - they cover you, regardless of what happens.
I've only been investing every so often for the past 3 years, but I am very proud of the profits that I've made. Nowhere else will you see such mind-boggling profits, if you become wise about how to protect yourself. No 401(k), no lottery ticket, no slot machine will make you this much money in a comparable period of time, if you stick with it. This stuff takes time to learn and understand, and I've heard of many people spending several hours a day for weeks, in the beginning, learning about technicals, and figuring out which stocks to choose to buy. I have no finance education from college, not even a mathematics degree, so I know that these profits can be had by everyone from every walk of life. Just don't give up, and tread slowly in the beginning. And never invest any amount of money that you can't afford to lose.
