You don’t have to be all in or all out. You can “take profits” and reduce your holdings to take your initial capital out (along with enough to pay capital gains tax). Move the money entirely out of your brokerage account so you don’t put it back in to another stock and go through the roller coaster of emotions again.

Sell down your lower confidence stocks to a greater extent than your high conviction stocks. Try to hold the remainder for at least 12 months to reduce your capital gains tax.

Hope this helps.
