Beware of confirmation bias: With penny stocks, beware of confirmation bias: the tendency to interpret information in a way that that conforms to your preexisting beliefs. This is something that afflicts nearly every human being and most new investors (or rookie poker players). Seeing what you want to see (albeit usually subconsciously) can be incredibly costly.

Dividend investing refers to portfolios containing stocks that consistently issue dividend payments year-in and year-out. These stocks produce a reliable passive income that can be especially helpful in retirement. Dividend reinvestment is a way to accelerate portfolio growth. Still, you can't judge a stock by its dividend price alone. Sometimes companies will increase dividends as a way to attract investors when the underlying company is in trouble. Dividends are taxable.

Have a complete 360-degree view of what you’re buying before you buy it. Fundamentally, take a look at what’s under the hood of the company with regard to earnings ratios. Technically, understand what’s happening in the short and long term with support and resistance. Know your exit strategy and your money management strategy, including stop losses.
The solution to both is investing in stock index funds and ETFs. While mutual funds might require a $1,000 minimum or more, index fund minimums tend to be lower (and ETFs are purchased for a share price that could be lower still). Two brokers, Fidelity and Charles Schwab, offer index funds with no minimum at all. Index funds also cure the diversification issue because they hold many different stocks within a single fund.
What would make me sell: Sometimes there are good reasons to split up. For this part of your journal, compose an investing prenup that spells out what would drive you to sell the stock. We’re not talking about stock price movement, especially not short term, but fundamental changes to the business that affect its ability to grow over the long term. Some examples: The company loses a major customer, the CEO’s successor starts taking the business in a different direction, a major viable competitor emerges, or your investing thesis doesn’t pan out after a reasonable period of time.
