Yes, times a thousand. But I would go even further.
Never give investment advice. You might explain what investments you have made and why you made them, but never give advice and never urge or prompt someone to invest. You should also end every conversation with "but that's not advice and I'm not an expert." It is too easy for either the investment to not work out, or for them to do it wrong (wrong timing, panic sale, misunderstood the options, etc).
The last thing you want on your conscience is someone investing a life changing amount of money just for it to go down in flames. I might invest $1000 in something that I think might pay off, tell someone they should invest, and next thing you know they drop in $40k and panic sell on a dip in two weeks, when I was planning to hold for five years. You never know.
