Yes, however: My father in law gave me some great advice: Pick a stock or two and put some small amount of your investments into it, like 1-5%. This makes the investing more fun. And he was very right, not the least of which because the stock I put $7K in exploded and ended up worth over $200K. ;-)

My BIL put money into Underarmor (he's an outdoors guy) and Electronic Arts (he's also a gamer), both of which have done good for him. My son put some money into Roblox (he's a gamer), and that's done well also.
