Congrats on the retirement. Living the dream that many of us dream of every single day. Getting rich is a long, (12 years is not even that long compared to 40 years in a job and still being poor), and boring process which requires a lot of hard work BEFORE you can position yourself to do just that. And yes, that's boring. But even with the ever fast moving world of crypto, it's the only way to go. Work hard, live small.
Enjoy what you accomplished and be proud of yourself! A bit of luck, but certainly courage, wisdom, and knowledge made you achieve this. Now time to enjoy the boredom of being 'old and retired'.
