You're learning important lessons from your experiences. That's great. The Stock market is quite a challenge and there is just too much too learn. Accepting to learn and make changes in your own shortcomings are equally important in this challenge.
From my own experience of many decades, I still am a bit greedy and that used to be a serious obstacle, and impatience at times caused me big losses... AMZN being hurtful. Still have some traces of both short comings, lol.
The problem is that the same lesson learned in one area is not always of positive and applicable also.
All I can say is that learning using stocks and in my case casino gambling (only Casino BJ), I have personally improved and aware to manage my own feelings and emotions to improve myself. I attitude over time changed and knowledge and understanding improved. And, Attitude is more important than Aptitude and a playful and happy attitude with better money handling and management I became a better "player" who now in retirement I enjoy much more. Having been a Project Manager/Engineer has helped me and I am having better fun now than when I was immature and responding poorly to losses.
fyi, now I hold TSLA shares since November 2020 that has increased in value more than 90%. Since it's potential appears to be good, I am holding will be holding cautiously long term. You have great opportunities in Biotech and in EV stocks, at this time. The larger market is as always tough to predict because it can and will affect all stocks if we get into a deep recession.
