definitely do NOT give up. I remember back when i was 16, i knew absolutely nothing about cars except that you had to put oil and gas in them. Once i got my license and got my own car i wanted to learn more. I got a repair manual for my car, and read pretty much the entire thing. I also got under the hood on mine and my friends cars as often as i could. I spent a lot of time reading posts on this forum and talking with people who knew much more about cars than i did. I'm 20 now, and i can't believe how much knowledge i have gained. Just be persistant and it will certainly pay off!!
