Sure, with you it is likely different from my own, yet I had considered all of my investments outside of bitcoin to have had been enough that I could have had used those in order to live off of them, so over the past 11-ish years, those outside of bitcoin investments have largely stayed the same, and maybe on their own they had appreciated in value to nearly double in value, while my bitcoin investment has performed in the 83x territories, if I were to use $1k per bitcoin as my average cost per bitcoin, since I may well be able to assert that mistakes were made and that is why I use $1k per BTC as a proximation of my average costs per BTC rather than using some other lower cost per BTC amount.
Mistakes are a valid part of our accumulation journey and we tend to learn a lot from them for those who are willing to learn from their mistakes and move on instead of dwelling in the regrets. Averaging at $1k per BTC shows you sold quite a good quantity which you got when it was below 1k and still continued buying to augument your portfolio for your unstructured sales even when the price surged well above 1k which is commendable and you've recorded good success and ROI of over 83x in your investment.
It's noteworthy that maturity on your investment takes quite some time and most times when you reach those maturity, you mentally setup more strict policies that guides you not to go back to your error periods which can be somewhat extreme, but necessary. Just like you trying to withdraw up to 10% yearly, but end up withdrawing only about 3% because of your possible innate desire to keep holding and not end up withdrawing to the extent that it wouldn't be termed sustainable.
Personally, I must admit that I've made mistakes earlier which I regretted and had to learn from and move on stronger and with more discipline and commitment to my accumulation journey and long-term holding plan. I kind of felt a good sense of belonging reading through your story.
