i took an entry level job in a shop and took a class at night, "basic machine shop theory". I work hard and never missed work. It cost money for a shop to train folks and the raises were nickle and dime, so I learned what they would teach me and after a year or two I went to the next machinist job I could find. I got a dollar raise each time I changed Jobs. I have 25 years in the trade now and the last three companys over the last ten years have said I was as good as they ever seen. remember your atitude will carry you far past your abilities and they will catch up later.
