I got my electricians licence a few years ago working in commercial construction throughout my apprenticeship, and since then I've been really thinking that automation, control, and programming is what I'm really interested in pursuing based on the little bit of experience I've had with PLC's in school and building automation systems in the field, and how much I like computers and technology in my spare time. Problem is, I'm not quite sure how to move my career in the path from basically only doing construction. Every job I see posted requires engineering or previous experience in this field. I'm 31 years old, and don't know if going back to school for 4 years is right for me. I was wondering if anyone had any advice on how to transition into this area? Should I head back to school in engineering? How do I get the right kind of experience? Are there any online course options that are attractive to employers? How should I be teaching myself this stuff in my spare time? Any good books? Any advice would be helpful. Thanks.
