I recommend this investment note written by $TSLA , a PDF booklet with a download link at the end.

As a retail investor, even if you do not hold TSLA stock, you can gain some valuable insights from it.
Especially the psychological fluctuations after early buying/selling, which resonate strongly when read.
Actually, "This is not a book about Tesla. It’s a story about an ordinary person deeply studying a company, enough to hold through the market’s worst headlines — and quietly and steadily add to their position when the world is selling."
The author, TeslaYoda, has invested approximately $500k in TSLA over ten years, with a holding value exceeding $6 million, achieving a true "ten years tenfold" return.
Technically, this also demonstrates the advantage of continuous dollar-cost averaging, standing on the side of time, buying in batches rather than going all-in at once.
164 trades in total.
And regarding taking profits, it’s also about selling in batches.
Selling due to fear of volatility and profit retracement is completely different from selling for taxes and daily life needs.
For the author, investing in Tesla is not just about money, but also about "faith."
Finding a belief target that belongs to each of us is very important — it could be another company among the Mag7, a key player in today’s AI industry chain, or Bitcoin —
The key is, you believe in this story and dare to bet heavily, and can hold for more than 10 years.
