Engineering is a great career. Starting salaries are very good and ppportunities abound in may specialties. If you prove yourself, opportunities and higher salaries will quickly follow. You can also see your contributions and feel part of a team that accomplished some great things. I’m my 35 years in engineering some things I feel great about were; new product introductions, improved safety and efficiencies in project management, and minimizing environmental impacts. I know you are concerned about stress, but being diligent and working efficiently can reduce stress. I think what is more important is that you persue a career that you are passionate about. Sometimes you will have hard deadlines and challenges, but if you like what you are doing, the extra work is not that much of a hardship. Good luck.
