I don't have any higher education, I took the vocational school route for electronics and IT support, got a job and worked my way up through experience and various courses/certifications. Maybe I'm a good example, because I used to be rather overweight (125+kg) and inactive. After I started working in IT, I've slimmed down to below 100kg and I've been doing crossfit for ~5 years.
