* Moving away at 18 to a new province. Best thing I ever did.
* Lost my job at 20, started a company. Never worried about money or looked back. This actually seemed incredibly natural.
* Shut down said company after 10 years, just to move on to more interesting things. No regrets. I'm working on way cooler stuff now in a variety of areas and I love all of it.
* Changed my eating/lifestyle, lost 35lbs. Keeping it off with no effort due to lifestyle changes.
I don't really pay attention to small stuff. I wouldn't say CD->iPod->iPhone was a deliberate change, more of a natural progression...
