If you enjoy understanding how things work and and applying them to real life things in an efficient, safe and cost effective way then engineering will be enjoyable. Work will always get busy at points and project deadlines will always exist but like Rodrigo said, if you enjoy what you are doing, you will gain experience and learn a lot. You can take general classes that apply to most types of engineering to start but math and science are important. There is a lot to learn but try to figure out which type of engineering you are most interested.
I am an mechatronic engineer, and I love my career and job, is not difficult if you love it, but you have to study a lot, and have some likes in fields such as, math, programming, mechanics, electronics, physics, etc, there a lot of fields so if you dont like one there are 10 or more types of engineers, my advice will to be sure what do you like, industrial things, mechanics, environment, chemistry and then investigate more about the jobs you may apply, but with the time you will acquire experience and knowledge, that will make things easier
