As you set out on your investing journey, here are a few common mistakes to avoid:

Don’t focus on the short term.

Treating the stock market like placing a bet is a strategy that probably won't work out for you. Successful investor Warren Buffett warns new investors against day trading. "If you aren't willing to own a stock for 10 years, don't even think about owning it for ten minutes," Buffett wrote in a letter to shareholders back in 1996. Buying and selling stocks quickly may get you a few dollars, but making a smart investment in a good company and sticking with it over a long period of time could make you exponentially more.

Don’t buy what you don’t understand.

Never buy a piece of a company when you don't understand how it makes money. Do your research and learn about the industry and the mechanisms that move it, otherwise the money you invest could disappear and you would have no idea why.

But don’t only buy what you know.

According to Investopedia, novice investors (and those with experience) should probably stick to the principle of diversification. In poker terms, you don't want to "let it ride" on one big stock in the hopes that your money will double or triple. Create a portfolio and spread the money around. As a general rule according to the experts, never allocate more than 5-10% to any one investment.

Don’t use your retirement money.

Risking your livelihood on investments is dangerous and ill-advised. If losing the money you are thinking of investing would ruin your life or the lives of those around you, then you absolutely should not do it.

Find good investments, not cheap ones.

In the same vein as the first tip, it's important for new investors to learn that just because they can afford to buy a stock, that doesn't mean they should. The idea of investing early in the next Google and riding the wave to wealth is enticing, but that's not a realistic strategy. Tried and true is often better than shiny and new.

And lastly, don’t overreact based on the news.

Hearing about a tanking stock on the news can be scary if that company is a part of your portfolio, but experts warn against letting your emotions get the best of you. Consider the history of the stock and whether or not the reason for the dip is something that could soon pass. If you panic and sell because of a headline, you could regret it next month when that dip turns into a spike.

  • Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
  • That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
  • We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
