Fantastic read and you should be proud of yourself. Not many people knew about Bitcoin at that time and you had the balls to invest allot of money in something that was pretty unsure back then.
Doubling your money is/was good investing, because its simply not that easy to double your money. If everybody could do it we all be millionairs.
I hope the motorcycle you bought with your profits brought you many nice memories, because that is something even bitcoin can't buy.
