The only time you really wasted, is the time you wasted with being unhappy. YOU are the one, that should be important for you, and not society and economy. According to society, my partner wasted 6 years by studying law, and then failing at a major test, and so being forced to end his studyings. Why are this years wasted according to society? "Because he could have earned money..." sh**, and instead of earning money we lived happily together during that time. Wow...that was really a waste. Additionally I wasted around a year in WoW. Why was that a waste? Because in that time I could as well have done a second job, to earn more money, money, money... Instead I was uselessly happy doing I like, what a waste.
Dont let others tell you depending on your own oppinions if you are wasting your time or not. Because its your oppinions to that, that matters. So as long as you are able to live on your own, its up to you to spend your time in the most meaning way, and that means in a way that makes you happy.
I like the way you think. Frankly, I'd choose a life of relatively comfortable leasure over a life of stressfull accomplishment any day. Keep on rocking on!
