I am going back to school in September, diesel engine repair. The auto repair shop I work at has two diesel techs working on the diesel pickups as well whom also work on vehicles. Both are looking to retire in a couple years. I have the money which is saved up from an inheritance I received 10 years ago I have not touched yet. 3 co workers and I are doing this and my boss is glad we are going to do this. At 46 years old, I still have it what it takes to do it and doing the night classes. I am not too old to learn new things and the young ones have learned from me. My husband is supportive and we had the talk on this. I am learning from these two as well working on them.They are glad we are doing too.
