I'm only about 95% invested into TSLA.
My girlfriend used to heckle me about having too much of my money in TSLA as well, she didn't think EV's were more than a fad and she
strongly wanted me to "diversify". That was back in 2018-2019 timeframe. She was like that until about January of 2020, which is when she decided to stop second guessing my investment decisions.
Now that I own a Model Y she's come full circle and even wants one of her own in the future. Of course I'll have to buy it for her, which ironically I could easily do because of my TESLA investments. The irony of that is not lost on her.
