Long ago, I got sound advice from my Great Aunt, a successful investor whose money eventually got to me when my mother died. I also read the same advice from Motley Fool and Richard Young. Buy and hold, especially dividend-paying stocks is the way I sleep well at night. It's worked out ok for me.
And remember that even if you stick money in safe non-stock places, inflation can eat up its value. You preserve capital, but lose buying power.
For a while, I played stocks a little with 'fun money' (money after investing in work-matched 401k and dividend stocks). But I was not good at it, mostly because I did not put in the time to do continual research and monitoring. And then you have to track lots more stuff and do extra work on taxes, which I hate doing.
It might be getting near time to do some value investing as stocks wobble around, but it won't be much money and it won't be daily buy-sell.
