Good luck in your future profession! I will add that I have a friend, who had always worked in the automotive industry. With the economy in turmoil, he found his jobs being eliminated and had to jump from one business to another, just to keep his income.
When he got tired of the long hours and small pay, he contacted a nationally known plumbing company. They set him up with some hands on training for 6 months, and finally gave him his own truck and equipment. Two years later, he could not be happier! He meets great people, always walks out like a hero for solving their plumbing problem, and makes great money.
Just remember, when the economy is in the crapper, so is the money!
