The most important lesson is never to get too greedy once your investment made a certain profit just cash out and move on rather than waiting on the big 100x profits that may never come and can lead to losses if the coin gets dumped.
Don't you think this statement was contradicted with your experience? your story was telling me that if you can become a long term hodl and the price will be even bigger rather than become the short term hodlers. That doesn't make sense if you are saying just cash out it once you made some profit but look at your story.
Take Hex coin for example I invested some amount in the coin when the project first launched with a very low price of 0.0005
Bought around 2 millions hex at this price
and I bought around 50k of the coin that was a $25 investment at that time but the same coin raised to 0.49 in 2021 before dropping back 0.24 at the present price, let say I sold my $25 investment of 2 years at the peak price of $0.49=$25,500 that could have been huge profits but guess what I sold at the $0.005 which is much less but lessons learn always make the right decision at the right time.
I have sold my stack at 10 - 20 cents price range. Good profit and then im jumping to another coin. that's proven that sometimes long term hodling was not too bad. So many millionaires came from the long term hodlers and you must see how long term ethereum and bitcoin hodlers have become new millionaires.
