Advice would be good

Hey so I started investing like eight months ago and I’m up 1k I’ve lost in, made some money, but most important I’ve learned that it’s better to use hold than to sell. I recently discovered that on every capital gain you pay tax. With the money you lose and the money you make with the money you pay in taxes you’re not really never winning. so I’ve decided to hold instead of buying and selling. I wanted for you guys to look at my portfolio and give me input on what stock to feed or what stock will be good to add that I’m missing. I’m ready to invest and let my money work.! I know there’s a lot of meme stocks haha that was the old me there’s no point of selling them now
