As others have said…
Start by selling half your stocks in the next month or two or so.
Begin by making a list of stocks that you don’t remember why you bought them or that you don’t think that they have good prospects going forward based on the current world events.
Buy an index fund with the funds.
Then read this board and others to get a handle on what else you should do.
I would choose to have a mix of more stable funds/stocks, dividend payers and more risky stocks (in your Roth).
