Heh. I don't think anybody has ever used the word "perfect" to describe anything related to me before. But if my example can serve as some sort of inspiration or motivation or something for somebody, then I've accomplished something useful in life. :-)

> I'm bringing my vehicle to a mechanic next Saturday (first maintenance not in the vendor). I'm going to ask him how to change the tires. So far I only changed the driver swipe so there is a lot to learn.

No worries. As the old saying goes "start with where you are." One great thing about the age we live in, is that there is SO much knowledge "out there" to be consumed and large swathes of it are free. When it comes to, for example, auto repairs there are so many Youtube videos detailing step by step how to do many, many of the common (and some not so common) repairs one might be interested in. And so on for a myriad of other interesting tasks. The only thing I'd specifically add is that if you ever start doing any serious auto work, really really put "safety first". If you need to get under your car for any reason, make sure to use jack stands (and get quality ones, not from Walmart!) and chock the wheels so the car can't roll, etc.
