history: I changed out my car's thermostat the other day. After watching a Youtube video on how to do it I felt assured I could do it myself.  I did some maintenance on my car and learned how to change out the thermostat. It was very easy using Youtube as guidance!
current: it's insane how Youtube and the internet overall are so helpful!
next: Seriously! I wouldn't have never learned this stuff and would of had to spend hundred of dollars at a repair shop!
