How is your 401k doing? Are you saving enough for retirement?
Do you have an individual investment account? What do you invest in? Individual stocks or mutual funds/ETFs? Actively managed or passive?
My opinion to get things started is avoid actively managed mutual funds. Evidence shows that they typically do not outperform passive funds (for the most part perform the same or even worse). But to make matters worse, the fees on actively managed funds are much higher. So even if they did outperform, fees will eat into whatever the difference is.
