Invest for the long-term
The point of investing is not to throw all your money in the stock market and make enough cash to buy a Bentley next month, even though that would be baller as hell. Rather, it helps to have a long-term plan to grow your money. "The best place to start [investing] is in your 401k plan at work," Bera says. "Oftentimes because you may get a company match." Many companies offer to match every dollar you put into the 401k up to a certain amount. That's beautifully free money.
If you can't get a 401k through your job, you can always sign up for a different kind of retirement account, called a Roth IRA, through a company like Vanguard. Once you put money in your Roth, you have to pick something to invest it: a Roth is basically a holding pen/tax-free zone for your money, not an investment itself. Once you have a Roth, Bera advises a "passive investment approach." That entails investing for the long-term. "I recommend [buying] low-cost index funds and target-date funds," she says. Those funds are a mix of stocks and bonds all wrapped up into one convenient investment. As another bonus, low-cost funds don't charge you a ton of fees to own them.
