Did your lifestyle ever change as a computer engineer?
Yes it does change and changed for the good. Now i spend more time in reading and am much more focused towards my career. I would suggest, get more exposure and keep learning, keep growing. (y)
Umm, my lifestyle did change...mostly for the better. For example, while I was in college, studying to be an engineer, I was waaaay low on funds :). Once I saw the light at the end of the tunnel ( that is graduation approaching), I began to interview for jobs and realized that there were many, many job opportunities that were available once I graduated. Once I graduated and took started my first job, for one thing, my personal funding situation got a lot better :). That good fortune just amplified the other exciting things about my job...some of the items mentioned in other answers, like meeting great people, working on great teams, solving business needs/problems and able to travel both domestically and internationally for my work.
To be clear, lifestyle changes are no fully dependent on the type of degree one obtains or type of job one has. These things play a role, for sure, but a bigger driver, in my opinion, is a person's desire to learn and that person's life curiosity. If you are open to learning and taking on new/positive experiences, it is highly probable that you will experience positive lifestyle changes.
Best of luck to you!
To answer your question I would say that your lifestyle will evolve at the same pace your career is evolving. When I was a young junior software engineer I dedicated a lot of time to my work, and tried to be as efficient as possible, that implied some extra work hours on a relative frequent base. Without saying that the adaptation from the student life to the real work life could be sometimes challenging as you'll have a lot of things to learn and adapt to.
But with time you'll gain confidence and expertise which will help you to get a more balanced life and gives you lot more time for enjoying your family life or your hobbies.
Lifestyle means different things to different people. I loved studying computer science. My work has taken me to many cities, I met so many people, worked under tight deadlines. Certainly the way I looked at life as a student verses the way I understand about life as a Professional is different. I prioritize more wisely now, make long term meaningful career plans and spend time with people I love and who matter to me and my lifestyle choices are those that reflects my values.
