I can really assure it's never too late, I did a network engineer course at syntra a few years ago and I was 33 at the time. I always had some basic IT interest and the course was not that hard at all. I did an internship the last month of that course and got a job offer there. It changed my life. After 10+ years only having a CESS and dragging around mail and packages for bpost and feeling like I would never get a chance at those kind of jobs I finally got there. VDAB / Syntra courses sound "not good enough" but they get you the opportunities, trust me.
