Having spent the last few years in a hybrid role ranging from security practitioner, to curriculum designer, and educator, I'd say that cybersecurity has the luxury of being both a challenging and enjoyable career field.
As far as 'good career choice', I can't accurately respond to that without knowing what a good career looks like for you. That being said, if we use # of openings + starting salary as metrics... it does look like a promising career. CSOOnline predict 3.5 million unfilled jobs in cyber by 2021
(https://www.csoonline.com/article/3200024/security/cybersecu...).
I'd recommend taking a look at https://www.cyberdegrees.org to figure out what roles interest you and the experience / certifications that will help you get there. Additionally, if you are looking for materials to read/learn/practice hands-on activities in security, I'll share the (constantly growing) list I've curated: https://www.exeltek.net/accesscyber.
Feel free to reach out with any specific questions you might have, and best of luck!
