When I was around eleven I developed a passion to be an Electrical Engineer, Through hard work and sacrifice I got my dream and i was working for the worlds largest engineering Company, General Electric. The problem I was doing a very high pressure job that left me stressed and eventually my health was effected. -----What I am trying to point out, you can have your "dream" and have it turn into a "Nightmare". There are many Engineering jobs and Mechanic jobs that can be rewarding without the Nightmare. Follow the passion instead of the money. I worked as a NASA contractor for years and I was happy as a lark. I decided to go for the money and regret it to this day. When you have green grass stay with it because what seems greener may wither with time. If it doesn't seem right, believe your instincts, most of the time you will be right.
