I say Yes and No. But really, it's more like "Sometimes a bad thing might lead to good later, surprisingly"
For me, My college advisors lied to me and withheld information, preventing me from going into computer science (which I really wanted), and leading me to get a degree in something I sucked at.
Well, I ended up working for a year, and although it sucked, I now am doing pretty well financially. Plus, I met a REALLY good friend when I eventually came BACK to college to do the CompSci (after finding out I actually could go into it), and then after talking to a GOOD advisor, I got right into university, and due to the timing of it all, I then met my girlfriend, who is totally freakin' awesome.
So yeah, I wasted 3 years of my life, but I matured a bit, I met an awesome friend, and I met an amazing girl. Fair enough trade, I guess. XD
