What do you do after the lesson?

Good day together am still in the apprenticeship until the end of January 2011 as a car mechatronics engineer I wanted to ask now with what you can still make good money? Is it worth it to make a master and then to make yourself self-employed? Open car trade what is worth it? To earn good money? Please answer I don’t know what I should do after the apprenticeship just a car mechatronics engineer I don’t want to stay!!!
