Anybody add extra to their investments with the drop today, or are you scared of the economy dropping more?

I added a lot, but was still hesitant due to fears of tariffs dropping the market further downward.

Did any of you invest a lot anyways, or are you still on the sidelines due to fears of the tariffs, and do you think it would have been better if I waited out?

I also debated between focusing on my indexes or NVDA stock. Mostly from what I've seen on reddit people recommend indexes, but I wonder if I'll miss on the huge jump upward of an individual stock too?
