Selling Tesla will get me approx $31k in value (-$3k loss). Should I continue to keep or invest in NVDA, AAPL, GOOG, AMZN for long term?

I also have 800 shares of NVDA which has generated a lot in return. $10k invested for 80 shares to $90k with 800 shares. I currently have 183 shares of Tesla, just tired of it not moving that much in the past couple of years
