One of the most complicated part of being an auto mechanic is the variety of automobiles. You would want to determine if you would like to specialize in only one make, model or if you want to expand your knowledge among the different manufactures. Also I have seen that a lot of companies require you to have your own tools, this can get expensive. I see that you are a student, many high schools offer a vocational program, you may want to see if you qualify and attend for a semester to see if this is what you really like. We need more skilled trades, so if you enjoy it, and put all you have into it, you should be very successful. Best of luck!
